In some distros it seems the GUI package manager looks for an internet connection and if it can't find it, it won't let you do anything, not even manage local packages. Is there a way to disable this internet check? I should at least be able to manage local packages and add/remove from cd. this becomes an issue in isolated test environments that have no internet access. I suppose I could packet sniff what its trying to access and emulate it, but I'm sure there's a way to just disable that check.
