Кстати

To remove a package and all its dependencies in one command, you can also directly pass the package name as argument to apt-get autoremove:

sudo apt-get autoremove vlc

If you prefer to purge the packages (to also clean up all configuration files), the way to go is this:

sudo apt-get autoremove --purge vlc

Because of complex dependency tree of vlc. autoremove only removes automatically packages which currently have no installed reverse-dependencies. That means as long as there are other packages which may depend on vlc's dependencies, they will stay. Those other packages are probably vlc-plugin-* packages which depend on vlc but get not removed with that first run yet...

However, if you keep firing sudo apt-get autoremove after that first line, apt-get should slowly start to realize that there's more to remove.
