I get this when ever i try and install anything with th Terminal:
    You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 gimp : Depends: libgimp2.0 (<= 2.6.12-z) but 2.8.0-1ubuntu0ppa3~precise is to be installed
        Depends: gimp-data (<= 2.6.12-z) but 2.8.0-1ubuntu0ppa3~precise is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
I added myself to the root group in the grub recovery mode. Then did sudo apt-get -f install and got this: 
Errors were encountered while processing:
 /var/cache/apt/archives/gimp_2.8.0-1ubuntu0ppa3~precise_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
