Help Installing Gimp 2.7.5 on Ubuntu 11.10

Solution 1:

In the meantime(I assume Gimp 2.6 is now uninstallable, I've also had this problem), you can try and use GIMP 2.74. There's not much difference from 2.75. It still has the Single-window mode and Text input improvements.

Solution 2:

You have 4 options:

Install from this ppa. <--What I think you should do
For directions on how to do that check here.
The landing page for that PPA tells you what other PPAs you have to add to get the 2.7.5 install working.

deb http://ppa.launchpad.net/gnome3-team/gnome3/ubuntu oneiric main

deb http://ppa.launchpad.net/ricotz/testing/ubuntu oneiric main

Installing a bunch of ppas may or may not completely fix it with dependency issues though.

Dynamically compile all the dependencies and have what looks like a normal gimp install, but could break other software. - don't even think about it

Statically compile all the dependencies and link it all in to one huge gimp executable. - possible, but not likely

Wait until the main-line dependency system converges at the package level you want.
