yah but it was too late because somehow kerberos was messed up. I will need to reload the OS to fix the proubs.

hence the need to use the script again

terdon

Damn. Can't you boot into a live session and just copy the old fstab over?

Elliot Labs

I did that and fixed it

but the kerberos stuff was messed up so i need to reload it because the packages are not purging properly

Rinzwind

@terdon hmm? what is the problem? there is a way to re-create fstab :=)

Elliot Labs

it looks like the new script is working

I will try it on one more VM before I remark it as the answer

terdon

@Rinzwind There is if the idiot who posted an answer with a syntax error at least made sure that his solution made a backup of the original before changing it :)

Rinzwind

3:05 PM

naa you can use blckid and mtab to recreate fstab ;)

Elliot Labs

it is ok. I am going to reload the server anywey

terdon

@Rinzwind only if your system is currently running and you have everything mounted

Elliot Labs

I did fix fstab and got the serverr to boot

I used kali linux to remount the MD0 array anf manually fixed the fstab file

@terdon I remarked the answer on the question

terdon

@ElliotLabs Cool, thanks :)

Elliot Labs

yw!

one last VM to test

gotta reload it. it already has the fstab mod

Rinzwind

3:12 PM

@ElliotLabs no you did not say that on askubuntu :+)

?

lol

@Rinzwind Say what?

kali is offtopic ;-)

@ElliotLabs bye

Radu Rădeanu

I just earned the "Yearling" badge! Let's party... <:-P

Avinash Raj

@Alex your avatar belongs to which game?

user58869

@AvinashRaj it's meant to represent a character mentioned in a game called star wars the old republic, but I'm not actually sure where the image comes from the game itself, probably a comic, fan art or something official. the character is called revan, here is a link with some details Revan

Avinash Raj

wow and thsnks for your info.

@RaduRădeanu i have some doubt about awk.

Radu Rădeanu

@AvinashRaj I have many :)

Avinash Raj

3:40 PM

don't lie.

you and terdon are experts in bash.

Radu Rădeanu

Let see your doubt and maybe I can help

Avinash Raj

yah

And my command to extract package names which have different versions in Installed and Candidate

awk '$1~/Installed:/ {var=$2;next} $1~/Candidate:/ {var1=$2;next} /Installed:/ { last=$0;next } END {if(var != var1) { print last;} }' ~/Desktop/fir

but it won't work.Any suggestions.

Radu Rădeanu

3:56 PM

I don't know if awk is the best choise in this case

you can start from:

grep -1 Installed ~/Desktop/fir | sed -r 's/(Installed: |Candidate: )//'

terdon

@AvinashRaj also, your next means that the line is skipped so the awk will not continue, so your 2nd /Installed:/ will never match.

@RaduRădeanu's approach is much better, but this does what you wanted it to do:

awk '$1~/Installed:/ {var=$2; last=$0} $1~/Candidate:/ {var1=$2} (/**/ && var != var2){print last} '

Avinash Raj

{var=$2;next} field no 2 will be stored in the variable var and next means, it moves to the next line. Is this wrong?

@terdon

avinash@avinash-Lenovo-IdeaPad-Z500:~/Desktop$ awk '$1~/Installed:/ {var=$2; last=$0} $1~/Candidate:/ {var1=$2} (/**/ && var != var2){print last}' ~/Desktop/fir
awk: line 1: regular expression compile failed (missing operand)

terdon

@AvinashRaj Strange, it ate my escapes when I pasted:

awk '$1~/Installed:/ {var=$2; last=$0} $1~/Candidate:/ {var1=$2} (/\*\*/ && var != var2){print last} '

Apparently, I need to escape the slash in the chat

Avinash Raj

@AvinashRaj Yes, those are the different versions.

Avinash Raj

I want the pacakge name which has differnt versions in Installed and Candidate record.

In this python3-problem-report: and python3-pyatspi: has differnet versions in their Installed and Candidate record. i want their names.

terdon

@AvinashRaj Oh, OK, your original version was not keeping the package name which is why I thought you wanted the versions

Avinash Raj

Dis somebody see my new avatar?

Guess who is that great person.

terdon

@AvinashRaj This will work but, really, use radu's much simpler than this approach

awk '{if($1~/Installed:/) {var=$2; last=$0} else if($1~/Candidate:/) {var1=$2} else if(/**/ && var != var2){print pack} else if(/^[^ ]*:/){pack=$1}} '

Avinash Raj

i love to learn hard things

@AvinashRaj I got this workink using a lot of seds

Avinash Raj

wow

Radu Rădeanu

:))

terdon

@AvinashRaj Yes, as I said before, you need to escape the *, the chat eats my escapes when I paste it. You need /\*\*/

Avinash Raj

where i have to give the file name?

At the end?

terdon

@AvinashRaj There is hard and there is needlessly hard. Don't try to do everything with awk, it is only good for certain things. Look how much simpler @RaduRădeanu'sw solution is.

@AvinashRaj Yes

Avinash Raj

4:33 PM

where i have to give the file name?

Radu Rădeanu

sorry, a small mistake:

Avinash Raj

where i have to give the file name?

Elliot Labs

4:39 PM

@terdon Just finished testing on the last VM it works great!

terdon

@ElliotLabs Cool :)

Elliot Labs

@terdon Thanks for all of your help!

Avinash Raj

terdon please post the solution and then i will learn from that.

@terdon @RaduRădeanu Thanks for your hard work.

terdon

@AvinashRaj Look at what you posted. What is the error you get?

@ElliotLabs You're welcome and sorry again about the original cock up

Avinash Raj

grep -1 Installed | sed -r 's/(:|Installed: |Candidate: )//' | uniq -u | tac | sed '/--/I,+1 d' | tac | sed '$d' | sed -n 1~2p ~/Desktop/fire

is this a corretc one?

terdon

4:43 PM

@AvinashRaj nope

What error are you getting?

Elliot Labs

@terdon Lol it happens I don't hold anybody responsible except myself for using something that I can't understand. But it now works and it works great! Iw ill use the new version of the thing that I can't understand...

terdon

That should tell you what the problem is.

Radu Rădeanu

@AvinashRaj grep -1 Installed ~/Desktop/fir ....

Elliot Labs

What is his proub?

terdon

@ElliotLabs Glad you're not keeping a grudge :). Nah, it just annoys me, I should have known better.

Elliot Labs

4:44 PM

@terdon lol it is fine

terdon

@RaduRădeanu Dammit, you broke my Socratic teaching approach :) I wanted @AvinashRaj to see the "no such file or directory" error

Radu Rădeanu

sorry

terdon

@AvinashRaj yes, the file should be at the first grep. When you asked me before, I thought you were asking about the awk.

@RaduRădeanu :) just kidding

Elliot Labs

THANKS!

Avinash Raj

works :-)

Good Job!!!!! Woot Wooot Woot!

@RaduRădeanu

go and get a cake!

happy birthday!

hbdgaf

The cake is a lie. Always.

Elliot Labs

assuming that yearling means that you have been here for a year....

@hbdgaf ?

hbdgaf

4:52 PM

"the cake is a lie. Roughly translates to "your promised reward is merely a fictitious motivator". Popularized by the game "Portal" - meme

Avinash Raj

And finally the command to get the list of packages which needs an update.

dpkg --get-selections | xargs apt-cache policy {} | grep -1 Installed | sed -r 's/(:|Installed: |Candidate: )//' | uniq -u | tac | sed '/--/I,+1 d' | tac | sed '$d' | sed -n 1~2p

@terdon @RaduRădeanu ^^

It would be an answer for askubuntu.com/questions/99834/… question. Credit goes to Radu and terdon.

Elliot Labs

@hbdgaf can you get me the meme?

hbdgaf

you could google for it

Avinash Raj

I'm going to leave. Bye :-)

Kinda cool and kinda silly if you ask me.

Elliot Labs

@Seth Yah

@ElliotLabs Healthy eating and lots of exercise.

@ElliotLabs One answer at a time...

@Seth Yay :)

Elliot Labs

lol

it a TON

of points

hbdgaf

You climb a mountain one step at a time. The bonus is, after you answer a significant number that aren't version locked... it's a rep factory that just generates points without answering anything else because your answers are still useful.

Elliot Labs

@hbdgaf Version locked?

hbdgaf

How do I get software XYZ working on some Ubuntu version vs How do I block ICMP with iptables. One is only useful for a short period of time. The other one stays useful.

thanks!

5:22 PM

o/ @Mateo - I started playing Morrowind again a little. Thinking about seeing if save files are round trip compatible between openMW and Morrowind in wine.

Mateo

@hbdgaf that would be amazing, if they are just using the resources - in theory it should work

hbdgaf

Devising a new save pattern would be more complicated than taking the old one apart I should think.

Mateo

yeah, I remember when I could play original playstation games on the psp - and swap saves between them... then they started "updating" the psp

hbdgaf

Well, openMW is still a little new and I have Tribunal and Bloodmoon installed... so I don't really expect it to work. Would be awesome though.

One of my friends is more than a little upset his 12.04 install failed a PCI compliance scan. Is openssh 6.6 in a ppa for Precise anywhere?

blade19899

5:42 PM

For the people that play Morrowind:

How do i install OpenMW - EuroBytes

OpenMW is an game engine based on that of Morrowind, an RPG game from 2002. Although its still in Alpha, it works. It and its editor(OpenCS) has been written completely from scratch. Do you like Morrowind? then you are gonna love OpenMW

hbdgaf

Yeah, that's what got us on the topic of morrowind in fact. This conversation started yesterday.

blade19899

Really?

Mateo

@blade19899 ;)

blade19899

I haven't been here in a while

I just wrote that

Amma put that on AU two

17 hours ago, by hbdgaf

If anyone is watching openMW they were nominated this month for game of the month project. vote if you care ;) http://www.linuxgameawards.org/game/openmw

Mateo

5:44 PM

your going to make me dig out my old computer to find my save files :)

blade19899

Ah

Yeah just saw that today, then thaught to write about it on me website, instead studyin for yet another exam

hbdgaf

I'm done with exams. I just study to learn things now.

I've long said schools should just do that from the start. Have core tracks and competencies and let students pursue what they find interesting/fun, so we get people that are horribly good at any given thing and get placed in what they're good at doing instead of forcing a curriculum on them and making a bunch of well rounded meat-blocks to compete for the same jobs...

Nathan Osman

@JorgeCastro: When you're around, I think the MySQL charm is broken. I wrote about it on Discourse (under the Digital Ocean thread).

Mateo

hbdgaf

@NathanOsman I noticed you mentioning that. It's a shame something so critical is broken. Is there a reason you prefer mysql to postgres?

Mateo

5:53 PM

there is my old computer ;)

hbdgaf

@Mateo It's still pretty.

Mateo

3.2 p4 with a ATI AIW 9800 pro, best you could get at the time

hbdgaf

It's similar to my old rig except I had this: newegg.com/Product/Product.aspx?Item=N82E16814129141

Mateo

ah, this one was before pci express

the board is a asus p4p800

hbdgaf

My mainboard was chosen based on being made by ASUS or MSI, max processor, AMD video, max ram possible, and being in the daily deals on newegg. I don't remember what board it was, but it was a steal at $350 for board, case, RAM, HD, and PSU. Add on another $50 for a second PSU and another $300 for the video card and voila. Budget beast rig.

I bought two of the daily deal and sold the second one at enough markup to pay for the enhancements to my own.

Seth

6:03 PM

I can't for the life of me get the VB guest additions to install on my Trusty VM.

Check @Fossfreedom's blog. He blogged about getting it working.

IIRC he had to install a specific version of gcc or something.

Seth

fossfreedom has a blog? News to me.

Oh indeed he does.

Q: How do i install OpenMW

OpenMW seems like a great game, and which reboots a classic, but What is it exactly, and how do I Install it.

games

hbdgaf

@blade19899 have some votes...

you might want to add how to rip the assets out of a wine install of morrowind.

Mateo

@blade19899 yeah how to transfer save games ;)

hbdgaf

@Mateo that too

I'ld do assets first though. It's a bit useless to install an engine if you don't know how to move the game assets around. Then it runs. For people that have savegames, it would be doubly nice not to start over.

/me needs to start making project blog pages on github.io

Nathan Osman

@hbdgaf: I prefer PostgreSQL.

It's just that I think the WordPress charm only works with MySQL.

hbdgaf

Oh. Another reason not to use wordpress ;)

Nathan Osman

6:32 PM

I was never a huge WordPress fan.

Okay, maybe a long time ago I was...

...back in my PHP-loving days.

Braiam

@terdon or use backticks awk '$1~/Installed:/ {var=$2; last=$0} $1~/Candidate:/ {var1=$2} (/\*\*/ && var != var2){print last} '

Seth

@hbdgaf There isn't a VB version for Trusty, so I'm stuck. The Saucy version wants a 3.11 kernel.

Braiam

in Tavern on the Meta on Meta Stack Overflow Chat, 29 mins ago, by Louis

Maybe we should have a badge for people who post questions that manage to hit 5 different close reasons. Being bad in a way that makes it so that the voters can't agree on what is the worst in the question is kind of an achievement.

wow

someone does not understand the meaning of badges

badges need to be about showing how well someone is using a site as it is to encourage good behaviour

Nathan Osman

6:55 PM

Can we have a Bitcoin-miner Juju charm? :P

Seth

@fossfreedom How did you install VirtualBox 4.3.10 on Trusty? It won't install on my machine because it wants the 3.11 kernel headers.

Rinzwind

@Seth USC has 4.3.6

Seth

Yeah but I need the latest.

Nathan Osman

PostgreSQL charm fails to install as well.

Rinzwind

@Seth ubuntu is not about bleeding edge >:-DDDD

blade19899

@hbdgaf I had it installed ages ago. But, didn't do nothing special with OpenWM to get it working. Am assuming it automatically searches for it.

@NathanOsman I'm not happy about this.

Pretty sure it is unbiased :P

What is a good phrase for a "I failed" moment?

Nathan Osman

8:18 PM

Why aren't you happy? I interpret the results this way: if Ubuntu is truly better than the others, why would anyone be looking forward to it? With the other choices, people are dissatisfied with the existing versions.

Braiam

@Lucio D'oh!

Nathan Osman

@Lucio: there's always "facepalm"...

But that's usually for someone else.

Lucio

Oh, right

This is my phrase:

no, that sounds soft

@Braiam I can't

@NathanOsman what you think about "failed heavily"?

Nathan Osman

8:33 PM

Heavily isn't a word as far as I know.

Maybe "incredibly"?

Lucio

I like that

Failed ridiculously?

Nathan Osman

Switch the words around and you might have something.

I don't know what an english may think about it :S

I'll go for incredibly

@Lucio Incredibly is a good way to put it. Failed to such a degree that it is incredible. So yeah, that.

incredible is not a good thing necessarily. it just means beyond that which is to be believed.
