I confirm that upgrade process (from 14.04 to 16.04) crashed on my laptop LENOVO G410 like Pilot6 said. I also booted with livecd 16.04, then chrooted to the system. In my case I did also execute fsck /dev/sda1 That was because my first partition ended up with a lot of INODE problems. Finally I was able to reboot Ubuntu 16.04 with GUI. There is more... I ran dpkg --configure -a When I tried to do this apt-get install -f at the first time I was not able to execute, because there was broken packages. Ubuntu offer the option to open with SYNAPTIC, so I did with Synaptic. At the end finally apt-get install -f again _____________________________ No part of this problem but at the end of the day I notice 16.04 is tooooo slow to boot. I did systemd-analyze blame I see a lot of packages with execution time bigger than 15 seconds I double check any swap problem it seems to be everything OK. _________________________ Ubuntu 16.04 is working, fortunately I didn't lost any personal file, but it was hard and long to rescue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1556446 Title: Ubuntu 14.04 crashes on upgrade to 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1556446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
