Hi,

I have used ubuntu 10.04 and 10.10 for sometime now.
Sometimes when I try to install a package , Ubuntu had warned me saying "require the installation of packages from not authenticated sources".
But I just installed those packages ignoring warnings.

Now I can't remember the packages I installed from not authenticated sources.
Is there a way in Ubuntu, that I can list all the packages I have installed from not authenticated sources? So I can remove them if I really don't need them.

Thanking you,
Chamal.

Maybe you added PPA or some other non-official repository.That doesn´t mean packages are not good.They are not from official repositories.I believe you install them for reason.If system is running well there is no need for package removal.
