checkbox-gui cannot be installed on Precise

[Po-Hsu Lin]

When I try to install checkbox-gui on 12.04.4, bumped in some dependency problem, seems that some packages were removed from Precise repository (I'm using the checkbox-dev ppa)

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

This is caused by our PPA packaging not supporting precise in all the packages. I started fixing it this morning actually. It should be fixed in the next few hours

This implies that you don't have the Ubuntu SDK PPA enabled. I will make instructions for that easier to see on the dev PPA page
