Just a general reminder: dpkg will execute all maintainer scripts contained in the package as root. Packages can also contain various other files that can have a big impact on system security, like system .service files, cron jobs/timers running as root, SUID binaries, etc., even if the program itself is (meant to be) run only as a regular user. If you care about the security of your system inspecting the .deb before 'dpkg -i' is always a good idea (e.g. with mc or so). If you are adding foreign repositories you are also trusting them for all package updates, for *any* package on your system. By default APT doesn't care from which repository a particular package is coming from, as long as it has the higher version, and that is easy enough to manipulate (e.g. with an epoch). A trusted repository could then easily substitute *any* package on your system (kernel, init, shell, etc.) via package upgrades. The repository doesn't even have to be evil, as it could always be hijacked by a bad actor. Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser
