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.

Title:
  Ubuntu 14.04 crashes on upgrade to 16.04

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  I have Ubuntu 14.04.4 with 'wily' HWE stack. File system i btrfs.

  Whed I try to upgrade to wily, the systym crashes.

  I get a black screen. I can't get to tty and Alt+SysRq+REISUB does not
  reboot the system.

  After a hard reboot the system does not boot either to 4.4 or 4.2 kernels.
  Not with systemd or upstart.

  Regarding btrfs, it does not have any errors and all snapshots can be
  restored.

  I saved a shapshot of the crashed system and I can provide any
  requested logs. Now I reported from a restored system.
