The following packages have unmet dependencies

I get this message sometimes when trying to install software. Like just now, when trying to install VLC:

The following packages have unmet dependencies:

vlc: Depends: vlc-nox (= 1.1.11-2build2) but 1.1.11-2build2 is to be installed

Now, I'm fairly sure I remember auto-upgrading/installing missing/auto-of-date software like this via the command line quite some time ago. I'd 'apt-get install' something and then add a flag that would make it auto-update/install the software/libraries for me if it found some outdated.

Can anyone refresh my memory?

Have you tried;

Code:

sudo apt-get install update
sudo apt-get install upgrade
sudo apt-get install vlc

... one command at a time?

Thanks for your reply, that wasn't it though.

I was looking specifically for apt-get -f install . Not that it helped; it turned out I had to tick some extra software sources in Ubuntu Software Center -> Edit -> Software Sources and then do an apt-get update .

So yeah.. fixed!
