ubuntu-restricted-extras fails install, breaks all installs

[Mizutsuki]

Hello,
I was trying to install ubuntu-restricted-extras package and apt-get install failed. I have lost the original error, but now I can't install anything else or uninstall anything else and when I do apt-get -f install I get this:

Is this a known issue? Are there workarounds/solutions?

Thanks all.

try sudo apt-get install -f
this might work
& then try to install other packages

Did sudo apt-get install -f and got this:

So I'm still not able to install anything.

Ok, I think I've got it fixed. I don't exactly know what I did, but I went into aptitude and I just played around with it a bit and now I can install stuff. Thank you.
