Open a terminal, and run:

sudo apt-get -f install

Please be careful about what packages it removes, updates and installs. If you are sure about it, answer yes and let it do its job. If you are unsure, post the full output here and I'll try to give you some advice.

It seems that you've added a 3rd party repository that is not getting very well with your Ubuntu version.

When adding 3rd party repositories, please ensure it is for the exactly same Ubuntu version that you are running now. Also, don't trust any 3rd party repository, since they can break your system.

thanks jorge ...but this command doesn't solve the problem but what did you mean by adding 3rd party repositories ... i'm a beginner in ubuntu .. can you help me? – azaer Jan 11 at 9:29
It seems you are using medibuntu, a 3rd party repository. You can read what I'm talking about on the Ubuntu wiki. Anyways, if that didn't solve the problem, please post the output by editing your first post. – Jorge Suárez de Lis Jan 11 at 9:34
ok thanks alot jorge ... i read about repositories and i solve the problem by remove the mplayer package ... is there is wrong with that?? – azaer Jan 11 at 12:14
Nope, mplayer is an optional player. Don't worry about removing it. – Jorge Suárez de Lis Jan 11 at 13:15
