@Suhaib reinstall with 12.10 live cd might be quicker(you can reinstall without formatting home and all your files in home will remain) But of course you do make a backup ;-)
That too :) :) But sometimes when I search for an answer I also end up on websites that I can call gems. I ended up on code.openark.org/blog because I was searching for a problem with mysql. Ended up reading that blog for the better part of 4 hours. It has sooooooo many cool posts :D
@Suhaib yes you can but you need to upgrade from a normal release to the next release to the next release. You can upgrade from lts to lts (and skip the normal releases in between)
I have a Toshiba laptop that was running Windows 8. I installed Ubuntu 12.10 and deleted Windows 8 in the install. Ubuntu worked fine until I shut the PC down. When I tried to start it again it would just go to a black screen. If I take the battery out of the PC and put it back in and turn th...
@Seth I have multiple bug comments depending on what kind of bug it is. My generic "catch-all" bug comment, for situations where I don't consider it valuable to provide any bug reporting information that is in any way specific to the situation, is:
###[Q]Question is a bug I recommend [reporting this as a bug](https://help.ubuntu.com/community/ReportingBugs). ([This question](http://$SITEURL$/questions/5121/how-do-i-report-a-bug) also has some good information about bug reporting.) This will probably be closed as off-topic, in accordance with [the FAQ](http://$SITEURL$/faq) and [this policy](http://meta.askubuntu.com/a/228/22949).
Then I have several others, for giving specific advice. For example, for reporting crash bugs (just keep in mind that sometimes people use the word "crash" incorrectly, so not all "crash" questions are crash bugs):
###[Q]Question is crash bug in Ubuntu 12.04 or later, should be filed as bug with backtrace Questions reporting bugs are considered off-topic for our site (see [the FAQ](http://$SITEURL$/faq#questions)). This should be [reported as a bug](https://help.ubuntu.com/community/ReportingBugs). You can [make Apport collect and submit the necessary technical information](http://$SITEURL$/a/244982/22949)--but still make sure to read the [bug reporting documentation](https://help.ubuntu.com/community/ReportingBugs) first, and describe the problem thoroughly in the bug report you write in the web brow…
For bugs in Ubuntu+1 (where giving crash-specific advice is not valuable -- this is best for non-crash bugs):
###[Q]Question is a bug in Ubuntu+1 Welcome to $SITENAME$! This should be [reported as a bug](https://help.ubuntu.com/community/ReportingBugs). You may also find [this question](http://$SITEURL$/questions/5121/how-do-i-report-a-bug) and [this one](http://$SITEURL$/questions/18641/theres-an-issue-with-an-alpha-beta-release-of-ubuntu-what-should-i-do) valuable. We'll probably close this as off-topic, as per [the FAQ](http://$SITEURL$/faq#questions).
@Seth here are several others. For example, I have one for "me too" answers that are actually attempts to report crash bugs. You can see all my pro-forma comments in plaintext or jsonp. I try to maintain reasonably up-to-date links to my pro-forma comments in my profile.
If you want, I can make a pastebin just with pro-forma comments relating to bug reporting--just let me know.
I was wondering why upgrade sometimes doesn't want to upgrade certain parts of the system, while dist-upgrade does. Here's an example after running update:
apt-get upgrade:
rimmer@rimmer-Lenovo-IdeaPad-S10-2:~$ sudo apt-get upgrade
Reading package lists... Done

Just remember one thing: never everEVER remove libc6 (the package) or libc6.so.* (the shared libraries). You will be dusting off your LiveCD if you do.
One of these days, I should blog about the time that I accidentally deleted libc6 on a running Linux system and managed to pull of an amazing set of hacks to get it back again.
@Suhaib Besides trying to download drivers from Precise, 500 errors aren't something you can change. That's a server error. 503 might resolve itself though, see: checkupdown.com/status/E503.html
Boy... what I would give to have a one-on-one session with a Debian packager... :)
I just can't seem to get this package to build properly on Launchpad.
We need to have a Debian packaging Q&A session at the next UDS - and we need someone who really knows their stuff to answer the questions... because I've got a few really strange edge cases.
For those who are not MOTU (people who maintain the Universe and Multiverse software repositories) and do not have plans of the "I will apply to MOTU by $date" variety:
What keeps you and others like you from trying to become MOTU? What makes you think you couldn't become one?
I'm referring ...
Do we have a canonical question about how to set environment variables? Or, if not, do we have one about how to set them permanently for all users? (This comes close but the question is not broad enough, it's only asking about how to set PATH. Also, I was hoping we might have an older question with more answers, presenting a wider range of techniques.)
@Rinzwind remind me to explain to you that I do actually get comment notifications, and there's no need to ping me in chat when you've comment-highlighted me.
I have downloaded the latest apache-maven3.zip file and extracted it to the folder:
/home/gaurav/Java/maven3.
I don't know how to set the environmental variables for maven - such as PATH and M2_HOME.
I tried below things:
export M2_HOME=/home/gaurav/Java/maven3
export PATH= /home/gaurav/Java/...
@Suhaib The phrase "canonical question" is widely used throughout the Stack Exchange network to refer to questions that fulfill a widespread need, such that it's expected that people will be frequently referred to them and they'll have many duplicates. I'm using the term somewhat more loosely than some people do--I just mean any good question that addresses that general question in a sufficiently general way, and thus can be a canonical question.
I'm not specifically asking for a question that anyone has put on any list of canonical questions. (Also, this is completely unrelated to "Canonical Ltd.")
@Lucio /etc/environment isn't really a script--it can only contain definitions for environment variables. Also, why is it hard to edit those files (especially /etc/environment, where it's one line per environment variable and there's already a line there to serve as an example)? On the other hand, most environment variable definitions should probably be at the user level--that is, not systemwide, and thus in files like ~/.pam_environment and ~/.profile.
Right, that's the line that's there to serve as an example. To add more environment variables, follow that example. VARIABLENAME="CONTENTS"
That doesn't carry over to using script files like /etc/profile to set environment variables (to be accessed outside of the script) though. In a script, you have to explicitly export the environment variable, either while you set it (export VARIABLENAME=CONTENTS) or later (export VARIABLENAME after VARIABLENAME has been set the way you want it).
@Lucio Yes. Like with most other recommended ways of setting environment variables, they get set when users log in. You cannot instantly modify environment variables for all running programs. (Every process has its own environment, its own set of environment variables.)
@Lucio You can update environment variables at times other than login. But there is no way to set an environment variable for all programs, instantly. And there should not be any way to do that, because then many programs would crash frequently. They depend on having a set of environment variables that can be accessed without engaging in special actions to ensure atomaticity.
On the other hand, if you just want your environment variables to be updated for every interactive bash shell (even if it is not a login shell and its parent's environment has not been updated), you can put a command in ~/.bashrc.
@Seth Yes, that means we support it. We support Ubuntu and all its official derivatives (and no other OSes, except to the extent that we interpret questions about them to really be about Ubuntu or one of its official derivatives).
@Seth Yes, definitely. It listed GNOME-Remix as an example of an unsupported derivative, so we can definitely keep open and answer questions about it immediately without waiting for any FAQ changes (provided that they're about a version of it that is supported, I'm not sure every version is now supported). But the FAQ should be updated to reflect the change, definitely.
This and that are totally different, and Ask Ubuntu moderators only have the ability to directly edit the first one. So the difference is quite significant. It's not that nobody stepped up. It's that that is totally different.
Since you're the author of that post, if you intended to say something different, you could edit it...or you could make a new post. (But it seems Seth is posting about updating our FAQ.)
@Seth I recommend doing that. Though I'm not sure the FAQ will be modified until 13.04 is actually offically released, since that's the version where GNOME-Remix becomes an official derivative.
On the other hand, it could be modified beforehand--practically speaking, we're allowing many 13.04 questions now, plus, removing it from the list of examples of OSes not supported here doesn't cause the FAQ to say anything that wasn't true before.
@Seth might also want to mention that the links to Ubuntu Code of Conduct and Ubuntu Leadership Code of Conduct lead to the same place - the COC 2.0, and that needs to be fixed too
Perhaps someone forgot to update the main page (or they are planning some announcement) since the derivatives team has "recognised" it for some time now.
Since Ubuntu Gnome Remix will become an official Ubuntu derivative upon the release of 13.04, I think it's time we update the FAQ to reflect that.
Currently it states:
This is not the right place for:
Linux Mint, Backtrack, Gnome-Remix and other Linux distributions (try our fri...

@Seth Looks good. I'm not sure we need to insist that all users of the site abide specifically by version 2.0 of the Code of Conduct. However, now that the CoC and Leadership CoC are no longer separate, some change needs to be made to the FAQ, and also to the Stack Exchange Network Terms of Service (though that should be dealt with by posting on MSO).
@Seth Well, once a change has been made to the FAQ, we'll all have a better idea of what the terms of service really ought to say. (Since there are different ways to solve the problem of the CoCs being separate until version 2.0, with different people having read different versions of it.) So the FAQ really needs to be changed first, before that's dealt with.

so I've been trying to get the /etc/rc.local script to run, and for the life of me, nothing seems to work.

I just customised Ubuntu 10.10 using Remastersys using 'dist' option. But, when I booted the custom iso image to pendrive & booted using it, the live desktop is showing up. But, how can I install it? There is no installer in the desktop. Can anyone help?
@TheLordofTime It has helpful upvoted answers (and consequently doesn't appear in the list of unanswered questions). Since it's answered, it's neither abandoned nor off-topic (since only new/unanswered questions about EoL releases are off-topic; we don't close the old ones).
@TheLordofTime That question should never be closed as abandoned, because it has upvoted answers that address the problem. Only unanswered questions, or questions where their answers are totally unhelpful and clearly don't solve the problem, are candidates for closing as abandoned.
No worries. :) But to more directly answer your question: That question is fine as it is (since it's not "unanswered"). Nothing has to be done to it now, in another year, or ever.
Yeah, you have to decrypt the message with gpg. (You shouldn't have to use the terminal for this...but I don't know if seahorse will decrypt a message.)

@Takkat The system remains largely usable during a release upgrade, though for some applications it should not be used (for example, it would be best to switch to a different server, to provide an important service). So if you're calculating in terms of productive time, you might get a different answer than if you're calculating in terms of total time elapsed from beginning to end.
A live environment can be used during installation but it isn't the installed, already-configured system.
@Takkat Ah. A fresh installation would probably have been more efficient then (especially since there's probably no need to create installation media--just have the VM use the ISO as its CD/DVD drive).
@Takkat Blank like this? (If so, the answers there should provide workarounds, but on a new system this is almost always due to a bug, so I recommend reporting it as one, against the compiz package.)
