You are about to add the following PPA:
 "Fairly Stable" releases for Darktable

Do not install a more recent version of Lensfun using another PPA as it will likely cause issues due the API changes. The lensfun package for Xenial on this PPA already has new lenses patched in.

Xenial (16.04 LTS) has some extra library updates available, as some relevant libraries shipped by Canonical for Xenial are fairly dated.

Trusty (14.04 LTS) has some extra library updates available, as the relevant libraries shipped by Canonical for Trusty are fairly dated. These extras will however no longer be updated, they will remain as-is.

Trusty will no longer be receiving updates after 2.0.7.

Precise will no longer be receiving updates after 1.4.2.

New Ubuntu versions will be supported within a week or two after their release. Please DO NOT contact me about that. Be patient.

Please do NOT contact me about providing updates for anything. I will update things when I see fit to do so. I do NOT do requests!

DO NOT INSTALL THESE BINARY PACKAGES IN DEBIAN.
