I wanted to install dependencies for dropbox, and I found apt trying to
remove some quite important packages... Note that in the remove section there
is compiz or vim... How to proceed, safely, with the apt? I use Ubuntu 12.04 LTS

$ sudo apt-get -f install 



Reading package lists... Done Building dependency tree       Reading state

were automatically installed and are no longer required:
