Error when trying to install GIMP in Ubuntu
When trying to install GIMP from the Ubuntu Software Center,
I get the error "Requires installation of untrusted packages" and "The action would require the installation of packages from not authenticated sources."
In the details it gives:
gimp gimp-data libbabl-0.0-0 libgegl-0.0-0 libgimp2.0
Anyone know how to solve this?
