The Darktable PPA doesn't work in Karmic for me. The PPA page only lists Maverick and Lucid in the drop-down for sources.list entries, but everything else implies that it works on pre-Lucid releases. Darktable home page states it has been successfully tested on Karmic.

I tried adding the ppa via the apt command, adding via the gui "software sources," and adding manually in my /etc/apt/sources.list then doing a sudo aptitude update. When using the gui, then allowing it to reload, it gives an error about not finding what it's looking for. After any of the methods, the result is darktable is not found as an available package.

Has anyone been able to get this to work in Karmic?
