I had a similar issue - this was seemingly caused by api mismatch caused by a wrong epoch on the libdrm package in edgers.
Follwing the instructions on https://launchpad.net/~xorg- edgers/+archive/ppa fixed the issue for me: All: libdrm's epoch was accidentally bumped in this PPA, if you updated between 05-12 and 05-16 please run this command to fix it or it will no longer update! Sorry for the inconvenience.
