Actually, i'm going to to take it to a community that is more suited to answer it.

RobotHumans

Panther answered the question in quite a straightforward way. He's not a maintainer of the vlc ppa or daily build repos, so it's not really his problem anyway. If I was running daily, I wouldn't even try to run ppas. It's begging for trouble.

Q: What is the root cause of "E: Unable to correct problems, you have held broken packages."

Previously, I was getting this error when I merely tried to update. I believe this problem is related to the VLC PPA which has always been total and utter trash on Ubuntu.

Q: A command-line clipboard copy and paste utility?

In Windows I used command-line clipboard copy-and-paste utilities... pclip.exe and gclip.exe These were UnixUtils ports for Windows (but they only handled plain text). There were a couple of other native Windows utilities which could write/extract any format. I've looked for something...

all i can tell is that under Xorg xclip wors still

dessert

@Videonauth the Xorg session will still be available in 18.04, won't it?

thanks for testing and good morning btw ;)

Videonauth

erm i can tell you in a second, i just fored up a 17.10 VM with wayland to test if theyre working

but to be honest since both tools are based on X i heavily doubt that they work

dessert

@Videonauth Yes, me too! That's why I want to set a bounty now, so that people have enough time to find a Wayland equivalent before 18.04 is out.

Videonauth

well it seems basic xclip seems to work

dessert

really? yay! =)

Videonauth

10:39 AM

the two lines saying test was me simply pressing ctrl+shift+v to test

dessert

@Videonauth great, thank you very much!

Videonauth

shall i test xsel too ?

dessert

now I don't have to worry all of my scripts will fail to work in Wayland at least for this part :)

Videonauth

well i use an alias most time wanna know it ?

dessert

@Videonauth if you want – it would certainly improve the answers (I would add this information there then)

@Videonauth an alias for what?

Videonauth

10:42 AM

alias toclip='xclip -sel clip'

i normaly do cat file | toclip

dessert

I'm just writing a script for remind notification with using yad, where I want the content of a certain variable to be copied into the clipboard…

echo -n $var | xclip -f -se p | xclip -se c

Videonauth

well xsel works still too under wayland

(note: that is a completely unaltered 17.10 installation which is only updated to the latest proposal)

dessert

@Videonauth amazing :>

Videonauth

so, now to your question if xorg is still on 18.04 :)

fires up 18.04 VM

i would say yes ;) since i get a cogwheel at startup to choose between Ubuntu or Ubuntu on Xorg

:)

Still upsaet with wayland tho, reading "wontfix" on requests to support screenrecording and vnc software makes me upset

muru

10:57 AM

@dessert applications can freely write to the clipboard (aka copy). Only the application with focus is notified that the clipboard has been modified and can read from it (aka paste). Worse, the clipboard for applications running under the XWayland is independent of the clipboard for native Wayland applications, so something needs to sync them (IIRC the KDE KWin window manager does this, not sure if GNOME Shell does).

Informative read:

blog.martin-graesslin.com/blog/2016/07/…

Videonauth

true i not tested pasting in other windows except the terminal

dessert

@Videonauth That's what I thought: Wayland may be the future, but I will stick to Xorg as long as it's not possible to properly control it from the command-line.

Videonauth

I think the OP wanted more than this site generally provides or the question morphed into too broad in the comments

And perhaps some of the comments to the question also, but some are / were helpful

RobotHumans

3:44 PM

@Panther - I think he wanted to install a daily build of VLC that doesn't exist because of a bug in the way it got pushed to launchpad. So, an unsolveable problem that can't get answered beyond download the source and build it yourself or open a bug on launchpad. Your answer was perfectly sufficient imo.

Good on you for entertaining the question at all. I just ignore questions about daily-builds, because my answer would be "Wait a few days, and it will work itself out"

Panther

@RobotHumans - Thanks for the input. I think he may have been able to solicit help if he was not so frustrated =)

RobotHumans

It would be an interesting feature to tack on to the launchpad build system to ensure that every package is installable, or even though it's built - just not present it to users. So, if there's an unsolve-able dependency because A got pushed before B, then the package is just hidden on the back end.

Panther

They have a testing framework to do that, but it is not automated

and generally the -daily ppa are for testers , developers, and packaging not end users

RobotHumans

Yeah. See where I basically said "you don't get to complain about daily-build."

Panther

If you are interested wiki.ubuntu.com/ProposedMigration

packages will move a bit faster if they are security related

I broaden that a bit - "you don't get to complain about ppa" lol

although some ppa are better maintained than others

RobotHumans

3:57 PM

A recent update on arch bricked some people, because a systemd dependency borked. I use PPAs, but expecting daily build on Ubuntu to just work is like begging for trouble. And I don't complain if one goes wooly.

Panther

Ouch, I hate it when arch updated create bricks

Happens with any distro at some point, seen it with Ubuntu and Fedora as well

RobotHumans

Yeah. The faster release cycle in Arch makes it happen more though. I like the release cycle now, and I don't mind using arch from time to time, but I would never run arch edge on anything critical.

@muru so, NerdOfCode and NerdOfLinux turned out to actually be one and the same ?

The previous time, yes. Nobody seems to have taken action this time, so probably they're playing it safe now

Seems so anyway, not sure what the mods saw or did

dessert

How can I test whether a file's last line ends with a newline character? I want to append text to the file, but I can't be sure I always end the last line with a linebreak – and I don't want to create empty lines, needless to say.

terdon

7

A: Print all complete lines of file

A simple approach is to use perl: perl -ne '/\n/ && print' file If you just want to check that the last character of a file is a newline, you can do: tail -c1 file | grep -q '^$' && echo yes || echo no But the -c option is not POSIX, so it isn't portable.

Sergiy Kolodyazhnyy

Heh, these two accounts have been around for a while and theyve been mentioned in chat before. It's funny mods haven't looked into it earlier

terdon

@SergiyKolodyazhnyy Don't make assumptions.

@dessert alternatively, if you just want to check manually, you can do:

$ tail -c1 file | od -c
0000000  \n
0000001

Sergiy Kolodyazhnyy

5:18 PM

@terdon Oh ? Mods werk in mysterious wayz

Sergiy Kolodyazhnyy

@dessert you've been doing it already with your while loop, actually. That || [ -n "$line" ] part

@terdon I think I asked before but forgot. Can mods see IP addresses?

dessert

5:21 PM

@SergiyKolodyazhnyy That does the trick for the loop, but for echo 1 >>file it's not useful…

@SergiyKolodyazhnyy yes but our access is monitored

muru

Sergiy Kolodyazhnyy

@dessert OK, I'm waking up so still i don't quite understand what you're trying to do

dessert

$ echo 1 >nl
$ echo -n 1 >no_nl
$ echo 2 | tee -a nl >>no_nl
$ cat no_nl
12

terdon

@dessert this should fix all lines that don't end in a newline and leave other files untouched:

perl -i -pe 's/$/\n/ unless /\n/' *

dessert

5:31 PM

That's the problem – of course I want 1\n2 there, not 12. terdon already solved it with tail -c1 though. :)

terdon

Test it first

I only tested on a couple of examples.

And you can make is safer with perl -i.bak -pe 's/$/\n/ unless /\n/' *

But that means a .bak backup of every file, changed or unchanged.

So I finally went with a small 2 in 1 laptop. I didn't look hard at its ability to run Ubuntu out of the box, but I figure worst case scenario I can use the Linux subsystem.

Sergiy Kolodyazhnyy

Also, BSD. I kinda want to dive deeper into that. Especially, ghostBSD. Desktop oriented, comes with Mate by default

Because that's bugging me on my big laptop.

I don't think Firefox runs on Windows 3.1. Although some older versions of Opera do.

Opera 3.62 apparently supports Windows 3.1.

Hey all - Got a question on viability of a procedure. Looking at this tutorial to create a 64g persistent USB install of Ubuntu for use with a Surface Pro 3. This will mostly be for study/experimentation towards Linux+ certification.

Thoughts/ideas/better links?

I'd prefer not to create a dual boot.

RobotHumans

10:39 PM

I'm unsure whether UEFI on a surface pro 3 will allow USB boot. I know on my ASUS laptop, the particular UEFI implementation would not allow boot from USB devices. Further, it gave me some trouble in getting dual boot working even with dual UEFI partitions and a bootloader that supported both. It may work, but I don't have your hardware, and UEFI implementations are hardware dependent.

Seth

@JohnP I'm not familiar with that software. But it'll probably work. Surface Pros can be really hard to get Linux running on though.
