After doing a apt-get dist-update and restarting the pc because of some 
errors I'm getting the problem as show in the image.

can't dist-update and system is not working correctly, many missing 
libraries which I don't know how to reinstall since it doesn't allow because 
of deppendencies. I'm lost.
