My question:

I have installed programs through apt, as deb packages and used checkinstall. So all my programs are listed in synaptic and when I create the list using the original command.

However, what I would like to know is when I try to re-install everything will the programs that are NOT in the official repos install? What will happen say for the program avast4workstation? It is listed in the dpkg list but I downloaded it as a separate .deb file from avast.

Thanks in advance!
