Re: [Trisquel-users] I want Unity without VirtualBox. Proprietary scope.

If unity is in the repository then go ahead and install it, but of course  
remember that Unity has privacy issues. See

As for the other packages you mention, they may not be included for various  
reasons. Perhaps they weren't in Ubuntu at the time. Who knows.
