I have Ubuntu 8.04.3 LTS and ran this:
$ sudo apt-get install python2.7
I got this:
Reading package lists... Done Building dependency tree Reading state information... Done E: Couldn't find package python2.7
It can find python2.5, so I don't think I spelled the package name wrong. I wonder if it's because I'm on an older version of Ubuntu (2008). Is there a straightforward way to upgrade to Python 2.7 (or even 2.6) without upgrading my OS?
