Here is my problem: I'm using Lucid Lynx and would like to have the latest version of freeciv.
The latest version I can get without adding a PPA is 2.1.10-1, it is in one of the default sources (Don't know which, Universe or Multiverse probably). The current version is 2.3 or something.
I followed instructions on how to get up to date versions by adding
ppa:kgoetz/ppa to the list of the sources. No problem here.
After reloading the sources, the version I can install is still the 2.1.10-1, the one from official sources. From the Synaptic Package Manager, I could "Force the version", but the item is disabled in the menu.
My question is: is there a way to override or select a particular source when installing a software?
This question is, of course, not limited to my particular case but to a global use of software sources.
