In case anyone rebooted (like me) and ended up with a message like:
"Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)"
Just go to the grub menu, select Advanced Options > pick a previous kernel and boot, once you get the terminal, type:
sudo dpkg --configure -a
Or: Advanced Options > pick a previous kernel (in recovery mode), get a root terminal from the menu, run:
dpkg --configure -a
The upgrade process should continue. Once it's completed just reboot and the system should be updated.
