Adding the PPA of Gimp 2.7 to the software sources list

The first step in the process is to get PPA added to your software sources list. Go to

System > Administration > Software Sources

Go the the tab that reads Third Party Softwares tab and add the following lines one by one:

deb http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu jaunty main

deb-src http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu jaunty main

Next up we have to add the GPG security key. You can get the key by going to Signing key page (At the end of the post) and copying the text and saving it by the name of Gimp on your desktop:

Now go the tab that reads Authentication on Software Sources window and import the GPG key file that you just saved on your desktop.
