I had trouble installing MySQL server on my laptop. And now if i try installing anything new it gives an error message. I tried most of the sites but could not find a solution to my problem.

When I run sudo apt-get install -f I get the following message:

 sudo apt-get -f install

Restart your system, if the problem persists then run, in a console:

sudo rm /etc/group.lock /etc/gshadow.lock
