Status changed to 'Confirmed' because the bug affects multiple users.

Why Ubuntu still isnt stable.. It detects crash reports.. it is boring. I hope Ubuntu 14.10 will be stable like Windows.

I keep having this problem and yesterday I upgraded to 14.10 from console, and after install was made, I still get these messages. Anyone knows when it will be solved? Thanks

Also happened the same after upgrading from 14.10 to 15.04 . Unity is not starting automatically either
