Why isn't Ubuntu using the latest versions of some applications?
Whenever I use the package manager, it can only ever find really old versions of stuff. Example:
sudo apt-get update
sudo apt-get install postgresql
The best it can do is version 8.4 (3 years out of date). Trying to get a later version, I get:
$ sudo apt-get install postgresql-9.1
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package postgresql-9.1
I experience the same issue whenever I use the package manager, so I usually just download and build things from source.
How can I make it find up-to-date software?
