I have a new installation that has no chance of an internet connection.

Since I want to add a few development software packages, I downloaded a few *.deb files. The problem is that for every package I try to install I get the same error:

"Dependency not satisfiable...."

Also downloaded other versions of that software (the deb files) but it didn't work.

I've researched other questions in here and Google and I haven't been able to solve this yet.
