Q: Ubuntu, lua, nmap and sqlite3 - module 'luasql.sqlite3' not found

I need to work with nmap and sqlite3 and I installed lua 5.1 and lua-sql-sqlite3 on an ubuntu machine: sudo apt-get install lua5.1; sudo apt-get install lua-sql-sqlite3 Now, when I'm doing this: $ lua Lua 5.2.1 Copyright (C) 1994-2012 Lua.org, PUC-Rio > drv = require "luasql.sqlite3" > print...

@kos I accidentally tried to make a new primary partition instead of logical, that's what was happening

@TheBrownOne why is that bad? Are you not using EFI?

Wow I'm already 15 versions behind on Spigot

user139252

2:17 PM

Not on that particular laptop I wasn't

user139252

It's an old one I use for testing

What are you trying to do?

user139252

I was dual booting Trusty and Xenial

Q: mysterious out-of-space message from rsync

I am mystified by the out-of-space message from rsync - I have enough freespace on the destination to hold everything, and I blv enough also on --vg-root as well. This doesn't seem to be the same case I have seen reported, where a big temp/swapfile gets created in a location other than the ultim...

[ SmokeDetector ] Pattern-matching website in answer: Configuring keyboard hotkeys with same scancodes and different keysyms by user2882440 on askubuntu.com …

I need some help on /etc/sudoers.

The output of env -i sudo printenv is

SHELL=/bin/bash
MAIL=/var/mail/root
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
LOGNAME=root
USER=root
USERNAME=root
HOME=/root
TERM=unknown
SUDO_COMMAND=/usr/bin/printenv
SUDO_USER=pandya
SUDO_UID=1000
SUDO_GID=1000

and ` env -i sudo -E printenv` is:

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
LOGNAME=root
USER=root
USERNAME=root
TERM=unknown
SUDO_COMMAND=/usr/bin/printenv
SUDO_USER=pandya
SUDO_UID=1000
SUDO_GID=1000

Now suppose I want to remove one variable to be displayed, I used env_delete += "SUDO_UID" at /etc/sudoers` but still it is displayed in above commands

What am I missing?

Aslo, man 5 sudoers says env_delete will be shown in sudo -V but it shows nothing related to this:

Sudo version 1.8.9p5
Sudoers policy plugin version 1.8.9p5
Sudoers file grammar version 43
Sudoers I/O plugin version 1.8.9p5

Can you help me?

@kos do have you idea how this works?

3:14 PM

may @terdon knows?

Not really. However, I would guess that what you're trying is failing because SUDO_UID is set by sudo itself. It is not inherited from the parent shell. Therefore, env_delete += "SUDO_UID" doesn't do anything since there is no such variable in the environment when the sudo is run. If this is about the U&L question, the OP needs to explain what they're trying to achieve first.

SUDO_UID is just example. Actually USER, USERNAME, LOGNAME also not working

And how about env_file="/etc/myenv"?

$ cat /etc/myenv
USER=""

also not working

@terdon Then can't we clear/replace any of them?

oh! I found you've already involved (unix.stackexchange.com/questions/269472/…).

sorry for pinging

@badp oh, cool - looked like a number in a circle here :)

with another font choice it looked a little more like a double-wide character

3:34 PM

@Pandya Try a different variable. For example foo="bar" that will work.

user139252

I like the new software center in Xenial... but other than that, there's not much improvement that I notice

@TheBrownOne is it the gnome center?

user139252

Yeah, it feels nicer than the old Canonical one

user139252

Also, found this in my additional drivers dialogue:

user139252

4:14 PM

That's not there in Trusty...

user139252

In Trusty, I have an option for using different drivers for my wireless card

the USB creator now does more than just Ubuntu ISO
ZFS filesystem is an option during install

you can move the launcher

@Rinzwind that is something

user139252

Do I need the new unity tweak tool to move it?

@jokerdino for me it is. I am mostly blind left side. so I want my launcher on the right :+

4:23 PM

@TheBrownOne there is a new one?

@Rinzwind srs?

user139252

@Jokerdino No, I'm just tired.

user139252

I figured "new release, every package is new"

@jokerdino yes. born with it.

I totally should make a new one. Remind me or help me. ;p

@Rinzwind sadface

4:25 PM

@TheBrownOne let me know if it works or most of it at least.

@jokerdino want to hear the most idiotic about it?

Who here is good with bash scripts?

Oli

But is Oli here?

This is probably pretty simple, but I have no idea how to search it

Call him three times and he will appear.

Missing some graphics in the tweak tool...

when I was 8 we moved from amsterdam to roermond (both in the netherlands)
up to my 8th I visited a eye doctor in a'dam that claimed nothing was possible to do to the eye.
in Roermond doctor said: it is the nerves behind the eye that did not develop. If you had your other eye blocked for a year before your 5th year it would probably have fixed itself. We can try but I doubt it will work at your 8th year. Ofc. did not work :P

none of these images are loading. what is this

@jokerdino see news.softpedia.com/news/…

@Rinzwind me dont like

4:29 PM

My script launches a bunch of things at startup, like TeamViewer, VNC, Scales and SSHd

user139252

@Rinzwind I'm not able to find the option to move it

The problem is that both TeamViewer and VNC launch a window so they halt the script

@TheBrownOne where are you looking for it?

@TheBrownOne I would asssume at "appearances"?

Is there a way to let the script continue without having to close those two programs?

user139252

4:30 PM

Tweak tool and appearance settings in System Settings

@Zacharee1 something like disown or &?

@Zacharee1 nohup in front and & behind

( cd /srv/Scales ; sudo npm start ; sudo service nginx restart ; sudo service ssh restart ; export DISPLAY=":0.0" ; teamviewer ; sudo -u zw vncserver-x11 -ShowStatus)

@TheBrownOne it wont be in UTT because I only heard of it now.

shouldn't be hard to find the key and add it. But glade O_O

there is an option in dconf-editor called "launcher-position" :-)

How is the ape doing? Last I heard we were waiting on him for a release?

he got a job

(Mahesh was his name?)

Totally

4:37 PM

@jokerdino lol

user139252

Can't find this.. I'll do a Google

Well let me go get some breakfast.

@TheBrownOne you're running 16.04?

user139252

On a testing machine, yes

tempted to install 16 myself :P

Apparently I need 6 .deb files :P

Abhishek Bhatia

4:39 PM

Hi guys

@TheBrownOne, are you familiar with git, python, gtk and gsettings?

Abhishek Bhatia

I had posted this question in python, but it seems it is more related to an issue at the level of OS. Please kindly check.

I am creating an flask api on ubuntu server. My code runs on native machine (without apache)but why deploying it I get OperationalError: (sqlite3.OperationalError) unable to open database file. Code: #! /root/anaconda/bin/python from flask import Flask,jsonify, request from models import Users...

python database sqlite ubuntu flask-sqlalchemy

@AbhishekBhatia hi!

user139252

All but git. I only really know how to clone with git.

hmm, we can deal with that one later then

4:41 PM

@TheBrownOne git is easy.

/org/compiz/profiles/unity/plugins/unityshell/

try that @TheBrownOne ^

user139252

Yeah, that setting didn't show up until I installed some extra packages...

user139252

I had to follow this

What are people's thoughts on MC 1.9's PvP timing?

table widget ;)

user139252

4:46 PM

@Mateo That is not wine

too bad I cant get it to display a table on the summary

any ideas to hack a table

@TheBrownOne hm, it's not in the repo then?

I tried various unicode spaces

oh, maybe the classic "......" dots for spacing?

@TheBrownOne it does more than just wine ;)

going to call it the "Spirit Scope"

@TheBrownOne yeah, you can even run Mac programs with it ;p

oh, I see... they missidentifed that one :/

4:51 PM

lol

oh, well if the patch hasn't even been brought into Unity yet we can't add it to UTT.

you can try adding it and UTT will refuse to open.

missing schema and what not :(

Wasn't Mahesh fixing that?

lol

it should be fixed in parts of the code.

spaghetti code is still messy

:/

Well the UI freeze was 3 days ago.. I doubt 16.04 will allow moving the launcher to the bottom.

4:58 PM

hm, I think this looks ok:

user image

@Seth Canonical never wanted to move it to the bottom though.

but lots of changed.. I am no longer sure if they know what they are doing.

I think it got added to the krylin edition, and someone ppa'ed it

yep

oh, maybe I'll have the card background change depending on the wine color :)

Abhishek Bhatia

any suggestions?

5:02 PM

more ram?

buy system 76 ;)

never manually upgrade libc6.

oh about the question posted earlier?

Abhishek Bhatia

does anybody use thunderbird with gmail here? I am unable to get the labels Primary, Promotions in thunderbird.

Can't find any relevant good docs/tutorial

@AbhishekBhatia not me. gave up on offline mail years ago :P

yeah, same here.

5:27 PM

Why do we 400 posts in the first posts review queue? I don't recall it ever going above 100 in the past 2-3 years.

1 hour later…

6:38 PM

EOL: askubuntu.com/questions/745550/…

upgrading is still on topic.

@Seth OK, dupe :p

@muru ask on meta

Anyone know a good place to get cheap SSDs?

I'm not sure I would buy cheap SSDs.

6:48 PM

@Seth nah, just interested in stats. Do we have an upsurge in new users?

@Seth hmm

LG G4 for $240 on VZW: swappa.com/listing/XBU353/view

WANT

@Seth I thought you might :p

@muru Well it has been higher than it was pre-January: askubuntu.com/site-analytics

Trustworthy? jet.com/product/detail/…

6:50 PM

The only thing I don't like about the G4 is the gigantic display. 5.5" is HUGE.

@Seth Oh, yeah, I forgot 10k could see stats

@muru It's actually 25k.

That. :D

@Seth G5 has 5.3 if you want to wait until April

I don't have $$ for a new phone anyway.

I'm not a fan of the G5's looks though :/

@Zacharee1 amazon.com/Kingston-Notebooks-Ultrabooks-SMS200S3-120G/dp/…

6:52 PM

Wow

Nice

But do you think it's something that'll actually work?

For a little more you can get a Samsung one amazon.com/Samsung-850-mSATA-2-Inch-MZ-M5E120BW/dp/B00TGIVQ4G/…

What do you mean "actually work"?

@Pandya Do you have env_reset enabled?

@Seth They are very "meh" (:P), but it's a pretty amazing phone

@Seth Quality-ish

@Seth I don't know about Samsung: HQ, but always overpriced

Wow @muru, you were right.

huge spike in new users per my stats.

whoa

that's potentially good

6:55 PM

@Zacharee1 Kingston isn't bad. Samsung is supposed to be even better.

@Seth the problem is I really don't want to break $60. $65 could work, but $73 is pretty far over

@Seth Mind giving some number? I'm curious.

@Zacharee1 well you pay for what you get.

Of course :p

I wonder if it has got anything to do with MS starting forced updates to Win10. :D

6:56 PM

I see why it's so cheap though

It's almost 3 years old

@kos No, never.

@kos We had 10k new users in November. 11.7k in January.

and again in February.

@Seth :O

@jokerdino Seth gave that away. :P

7:00 PM

Wow, we've more than doubled our monthly new users since summer 2015.

@Seth nice

@Seth I think I like the Kingston one, since it has a 3yr warranty

It's nice, the problem is we have way too few reviewers.

I wonder if these numbers correlate with the Windows 10 release :P

@kos I think the base issue isn't lack of reviewers, it's just lack of users that stick around for moderation tasks.

@muru @Seth

:p

@Seth great minds, and all that

6 mins ago, by muru

I wonder if it has got anything to do with MS starting forced updates to Win10. :D

7:03 PM

We don't have that many regular users, unfortunately :/

Not enough to handle the garbage, anyway.

@muru oh, I missed that message!

@Rinzwind Heer Nederlandse

me took the plunge. 16 looks nice :-) found some small bugs :*

@Rinzwind beta

damn ubuntu software center :D

oh the update page is nice :-)

@Seth Yeah, in general that's the problem. I always only see the same (few) users in the CV and LQ queue.

7:07 PM

@Rinzwind isn't it GNOME now?

user136984

So nobody seems to know anything about this?

not me ;+)

@kos yeah.. I'm floating a few ideas around for that, but we'll see.

@ParanoidPanda maybe go somewhere where more people speak Japanese. Have you tried #ubuntu?

@jokerdino I've asked in #ubuntu-desktop if they are going to ship the launcher patch. My guess is no but you never know for sure.

user136984

@Seth: You mean the IRC channel?

the way it was worded on all the blogs I though the launcher was an official change :*

7:16 PM

@Seth Ok, just be aware that cookies would work for me. :D

@ParanoidPanda yes

@Rinzwind yeah me too. I didn't find out until today that it wasn't official.

snif :(

shutter does not work on 16 yet

wat

mir?

it crashes

user image

^nice :-D

@Rinzwind ah

7:19 PM

@Rinzwind Restart & Install not so nice

@muru yeah but you can update single apps AND see a nice description of the update

@Rinzwind nwtoy.png? How did you manage that?

there is also the normal update

@muru sorry? explain :D :D

@Rinzwind Read "new toy.png" :P

oh the name of the file? ehm

user136984

7:20 PM

@Rinzwind The one thing I don't understand is why it's giving us upgrades to the latest unstable development branch for GNOME (3.19)...

user136984

They shouldn't really being doing that I don't think...

user136984

I hope it stops after the release Xenial because otherwise that might cause a lot of problems...

It's probably just because it's in beta still

@muru no idea. I did not do that :X

user136984

And they're not meant to allow you to upgrade to the latest git versions...

7:22 PM

anyone here use smplayer?

user136984

@muru: Why do you need to use that button (Restart & Install)? Why not just use Terminal? I haven't used any form of Software Centre in ages, I think I even uninstalled mine... :P

@Rinzwind The one true player.

user139252

Boo!

@ParanoidPanda judging from questions I've seen here, that should break the OS

@TheBrownOne AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Desktop does not abide by users-dirs.dirs :X

7:23 PM

@ParanoidPanda I don't. But when it pops up saying Updates Available and asks to restart, :/

user139252

@Rinzwind are you trying Xenial now?

@Rinzwind what

user136984

@Zacharee1: Really? Oh, maybe I didn't then, maybe it was the Software Updater I removed... I know I removed something relating to that, I just can't remember what...

user136984

@muru: Can't you just upgrade using the package manager and then restart using the proper restart button rather than having anything to do with GNOME Software?

@ParanoidPanda But why? When Update Manager used to do this perfectly well, why can't I do so with this?

7:26 PM

ehm mpv media player? wtf is that

@TheBrownOne yes installed it on my notebook

user136984

Well, I guess if you want to use the GUI you're stuck with it, but I don't know why anyone would want to use the GUI most of the time... If I can get a CLI environment I'll just got for that...

@Rinzwind fork/clone of mplayer, I think

@muru it looks like it is installed. probaly along with smplayer :P

@ParanoidPanda I don't want to use the GUI. But I would rather that if it told me updates were available, then I could install those updates with it, without restarting the whole system.

user139252

@Rinzwind what bugs did you find?

7:28 PM

@Rinzwind smplayer needs a backend, and mplayer is no longer fashionable.

mpv might be my new fav. player :D looks nice

@TheBrownOne MCeeeeeeeeeeee

nag

@TheBrownOne I have my Desktop saved under /discworld/Desktop/ and removing it from HOME plus changing the .config/users-dirs.dirs does NOT update the desktop

user136984

@Rinzwind: Which one of theirs is that?

one of the few with 100% english lyrics _O-
oops. almost 100%

@Rinzwind: No, I don't like it when they use English lyrics...

cant remove the fixed links in the left bar to change them for my locations
shutter is bugged :X does not even start

user139252

@Zacharee1 kind of hard to play while on a plane

pretty slick that mpv :-)

LO 5.0

7:34 PM

@TheBrownOne wat

user136984

@Rinzwind: Is it better in terms of features than the VLC Media Player (what I have)?

@ParanoidPanda ehm

A combo of smplayer and mpv is.

Searching subtitles is easier than with VLC. So is setting a max volume > 100%.

user136984

Because it looks nice, but unless it's as good as VLC in terms of features I don't think I'd get it... Because I use most of VLC's features...

oh mpv has a drop and play feature

7:36 PM

Well, not max, exactly, but you can multiply the volume.

mpv has no features?! cant even find a "preferences" :D

@Rinzwind mpv, mplayer, mplayer2 are mostly command-line. SMPlayer, GNOME Mplayer etc. act as frontend.

i like my player with nothing but the obvious buttons like FF Pause Resume

but ... mpv does not even have a "Open" dialog _O-

that is -very- slick D: D:

time to fix my desktop :P

user136984

By the way, just out of interest, what do you guys think would happen to America and the world if Trump won and became President?

Life will go on.

7:40 PM

@ParanoidPanda nothing. in the past 97% of all claims made during the pre-lims never got realized

plus he still has to please congress and the senate

plus he wont. The "convention" is probably going to vote on the candidate and I bet they are going against him.

user136984

@Rinzwind I think he's different...

ha my desktop files are back <3

yay for symlinks!

user136984

Whether he get in or not, he's going to cause a lot of trouble... Some of which he's already caused...

oh they did fix the symlink bug from 15.10 <3

@ParanoidPanda that wall with mexico aint happening

user136984

Why not?

Q: terminal while highlighted/marked strg+c doesn't work

Anyone got an idea why strg+c doesn't work while there is text marked in the same terminal window? Strg+c in function of getting new empty prompt. I am running gnome with lightdm

command-line gnome

user136984

If he became president, he could probably do it...

What is an strg?

@muru string with a missing in

that would be a " missg"

user136984

Or a missing an... :P

@ParanoidPanda 1. he wont get the funding. 2. Texas is on the verge of turning Democratic. 3. The amount of mexicans comming into texas is actually LESS than that are going out of Texas.

Most of the Mexicans comming to Texas enter -legally-. They want to work in the US, Get paid a decen wage compared to Mexico and go back home with the money

user139252

7:46 PM

@Zacharee1 I'm on my way out to Texas at the moment

everybody knows that only the poorest and scummiest of people are those who can afford to live abroad and will be deterred by migration laws

@TheBrownOne ?

user136984

But he could cause major problems if he even temporarily stops all Muslims from entering the country, and couldn’t he do that @Rinzwind? I mean, he'd probably cause a riot or something...

@muru showstopper: mpv does not do resume? :(

I want Trump to become president!

7:48 PM

@Rinzwind Dunno about mpv by itself, but SMplayer with mpv can resume from position after closing

as soon as you tell a thief what they're doing is illegal, they usually just drop everything, give themselves in and apologize profusely

@ParanoidPanda ehm not sure about that. He probably needs congress to agree on that?

right?

Poltics are going to be much funnier! :D

@badp :D :D True!

@Fabby wasn't 10 years of Berlusconi enough?

we tried our best to give you guys a good show

7:48 PM

In Holland Wilders is going to be the biggest next election. and by far.

@badp Bush! Reagan! Berlusconi!

Aaah, those were the times!

...Berlusconi started in the Clinton era btw

user136984

@Fabby I don't know, I think he'd shake things up for better or worse (probably for worse)... But I don't think him becoming president is a good idea...

wtf mpv can display TWO subtitles at the same time? :X

@Rinzwind is this the sort of stuff that should worry me as an expat in Amsterdam-ish

or can I carry on worry-free

7:51 PM

@Rinzwind the primary and secondary tracks

user139252

@Zacharee1 you wanted me to play Minecraft

@badp You're not the target audience...

@badp well thing is. He does NOT let people join his fraction. He is a 1 man party that has backup in the "2nd chamber" but he does NOT have people to form a parliament even if he wanted

user136984

You know? There's one thing I know nothing about, Japanese politics, I should do more research into that...

@TheBrownOne No, why are you going to Texas? Is this that job thing?

7:51 PM

@Rinzwind true of mplayer, as well, IIRC

user139252

Oh, no

@Fabby go tell that to the non-EU expats in GB who are about to be deported

@badp you can hide at my place if the need arises :-DDDDD

@badp Worry-free is my best guess.

@badp O_o

user139252

I have a friend out there, she just got a new job and we want to celebrate

7:52 PM

@badp When did that happen?

@TheBrownOne ah, well good for her!

theguardian.com/money/2016/mar/12/…

mpv is the default already in smplayer. nice

@badp what's the logic behind that?

@badp Yeah, there'll always be policies that have that effect.

I left Russia before I was deported...

7:55 PM

@Zacharee1 "every job taken by an expat is a job an unemployed citizen could be taking up instead"

Tons of countries have laws like that...

:/

@Fabby tons of countries aren't doing well

@badp I'm not saying I agree, but I'm also not saying I disagree...

It's what happens when people want to protect themselves...

the Netherlands actually sort of has the reverse rule: if you come from abroad, and you have a degree, and you earn enough, then

7:58 PM

What they forget is that these low-paying jobs are jobs no noe wants!

the first 30% of your income is tax-free

@Fabby This

@badp yeah you 30%-freeloader! >:-D

@badp Wow

Why? (what was the reason behind that or is the 30% a general rule?)

LOOK IT THAT, IT'S LIKE IT'S A GOOD THING TO HAVE PEOPLE FROM ABROAD GO CONTRIBUTE TO YOUR ECONOMY

7:59 PM

cuz we Dutch rule @Fabby

WE DIDN'T TRAIN THEM, THEY DIDN'T COST THE SOCIETY ONE CENT, AND NOW THEY ARE COMING TO US TO WORK

THAT IS BASICALLY THE BEST - DEAL - EVER.

@badp I think your capslock is stuck :p

no need to SCREAM. :D
