Remove the old version of GIMP from Synaptic or in a terminal:
sudo apt-get remove gimp
Download and save all five GIMP packages from GetDeb. Double-click on the packages to install them, in this order:
- libbabl-0.0-0_0.0.22-1~getdeb1_i386.deb
- libgegl-0.0-0_0.0.18-1~getdeb1_i386.deb
- libgimp2.0_2.6.1-1~getdeb1_i386.deb
- gimp-data_2.6.1-1~getdeb1_all.deb
- gimp_2.6.1-1~getdeb1_i386.deb
Now you can start GIMP normally, from Applications->Graphics->GIMP Image Editor.
