Your sources.list is horribly mangled, missing CRITICAL repositories, and is therefore not usable. You're missing quite a lot of things you MUST have - at the VERY least, the trusty main repositories which were created upon Trusty's release; without these, you can't install anything. This is because trusty-security ONLY contains security updates; it does ...

If you run sudo aptitude remove vlc, it will detect possible conflicts that would result of removing vlc and suggests to remove all those other "hidden" dependencies which apt-get would have missed on the first run.

I recommend you check this file. Given the filename, I'd expect ...

I've already faced similar problems and I figured that in most cases the only thing you have to do is sudo dpkg --configure -a and then sudo apt-get install -f If that doesn't help, you should edit file /var/lib/dpkg/status and delete whole blocks of broken packages.
