I need specific (source or binary) packages from Debian.
Can I download the package using apt-get?
How can I add the Debian repository to my sources.list so it only gets used on a by case base? Without messing up my system by using the whole Debian repository?
How can I get the gpg key for the Debian repository to be sure the package was signed by the Debian archive?
(Please don't tell me, that the system may break. I am aware of that and couldn't care less, because I can easily restore a VM snapshot.)
