I upgraded from another version that I had earlier to make sure it wasn't happening before. 2015-06-08 12:55:47 upgrade dpkg-dev:all 1.17.23 1.18.1 Thanks, marked as such. Furthermore, this wasn't a problem in the past so something must have changed recently (TM) and I'm not sure what. Ok, could you try with an older kernel? Preferably the one from before the upgrade?
