Adding edgy-plf repository by hand did not break anything. I tried to add a repository via Synaptic but failed - for some reason the repository dialog only flashes and the python returns "Error: could not find a distribution template". Happens.
Anyway, seems something garbled the package cache (that's bad) and the crippling broke apt (even worse). -- [feisty] apt and aptitude crashing https://launchpad.net/bugs/73062 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
