Are you sure you followed these advises: https://wiki.debian.org/DontBreakDebian

maybe you would had been better off with some flavour of Ubuntu, Debian is cool and all but it's not for beginners, although if you read into it first - it's one of the most stable systems you could use.

I used debian because I'm most comfortable with it as it was our choice of server distro at the time.

Still, worrying about reading guide after guide before installing routine software from a standard repo is not something I want to do in my desktop software.
