I got all excited to see that my PPA updated recently, so I open Krita and...the Sketch brushes are missing! Remember these dudes?

Any idea what I should do? I tried purging and reinstalling, but no luck.

I'm on Ubuntu 12.04, using the standard PPA listed for installation: sudo add-apt-repository ppa:kubuntu-ppa/backports

I think that's a packaging error by kubuntu, Jonathan Riddell seems to have assumed that the sketch brush engine was exclusive to krita sketch. Check whether there's a separate kritas sketch package and install that. We already told him it was a mistake, so I hope it'll be fixed for 2.8.1.
