Had the same problem with a VPS that can't be upgraded to Maverick (even the new LTS images aren't always made available on time). Marius' answer did the trick to get me started, but it should be expanded upon: Add the PPA to your sources If you're in my situation, the simple advice of running add-apt-repository won't work for you. So let's do this the ...

... or run lsb_release -d which should give you the the description including the OS name ("Ubuntu" on an Ubuntu system) and the release number. lsb_release -c will give you just the codename (e.g., "precise" for Ubuntu 12.04 LTS). For the release number only, use lsb_release -r For all lsb version details, use lsb_release -a EDIT: Thanks Eliah ...

No, it's not considered safe to define 2.7 as your default Python interpreter in Lucid. And I don't think it will be in the future. There are no major version upgrades of any software in one release. So python2.7 will not replace 2.6 as the default interpreter. This kind of upgrade is only done between versions, within one - especially an LTS - there are ...

I have created a PPA that contains a build of GCC 4.7 for Precise here: ppa:george-edison55/gcc4.7-precise (Click here for instructions on using PPAs.) To backport a package from one release to another is a relatively simple process assuming you have a Launchpad account and have registered your GPG key there. Make sure you have the ubuntu-dev-tools ...

This is the epoch. It overrides the version in determining which of two packages is newer: From the deb-version man page: epoch This is a single (generally small) unsigned integer. It may be omitted, in which case zero is assumed. If it is omitted then the upstream-version may not contain any colons. It is provided ...

It's a bug. Run lsb_release -a in terminal, and it will show you the correct version that you are using. Here is a bug report.

Generally changes are proposed and debated by the community at the Ubuntu Development Summit. See, for example, the Maverick Desktop Application Selection blueprint. There are some rules; the application must be in the main repository (which means it will be officially supported) and it and its dependencies must fit on the install CD. Applications can be ...

What counts most here is not the "version" (e.g.Precise 12.04 instead of Oneiric 11.10), but the desktop environment that comes on top of the Ubuntu OS (Xfce/Xubuntu vs Unity vs KDE/Kubuntu). Beyond all these, there is one operating system. Sorry to disagree with people here, but I do not think that 1 GB of RAM is sufficient to run in full comfort (that is ...

It's actually 9.1. Saucy seems to be pulling postgresql* packages from Debian's unstable dist, where because of some version dependencies they had to make the 9.1 branch look like 9.3 to the package manager until 9.3 graduates from their experimental to their unstable distro. See here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707675 Especially ...

If you used GEdit and you havent disabled the backup function, then there must be a hidden file with name similar to your file but with ~ appended to it. So if your file name is somefile.txt then look for somefile.txt~ in the same directory. This is the backup file and will give you your files state before last save.

Use Anwar's answer to find the architecture. Now here is the explanation for your second part of the question. Below is the uname output: In my case I have installed a 32 bit version.

This is based on this tutorial, recommended by Glutanimate in a comment to the question for making a 'local' installation of a specific version. I will consider only the case of the deb files package (there are multiple such files archived in a package). To get the latest versions go here. To get other versions go here. (I found about this address from ...

binW's solution is the only solution for a problem like this where you have no backup or other versioning software in place. It is a one-time rescue that may help you this one time. If you save again, that backup will be replaced and you lose anything from before that backup. I hope this works for you. Generally speaking, if you need version control or ...

As far as I understand, the main reason is that no one did the work to package TeXLive 2010 and 2011 for Debian/Ubuntu. See Ubuntu Bug #712521: [Needs packaging] TeXLive 2011 (especially the comments) for some background information. The current advice (from the TeX community) is to install TeXLive 2011 yourself, either instead or additionally to the ...
