I have a similar problem.See attached log
@GatesHater52 Sorry cant view fule right now, if you can post the contents.. if its long the last few lines will prob suffice.
If its not the dkpg message, it may be related to a ppa you've added, removing the ppa and rerunning updates usually corrects.
Looking at my previous posts will direct how or the manual will instruct.
If not ppa error may be a key file message i believe...A quick forum search should yield results to correct...
