Public bug reported:
My ubuntu system locks up regularly. Bugs I've reported about this get
closed for inattention, after being ignored, and queries about how to do
basic debugging get the same treatment, so I just power cycle whenever
it happens again.
This time the lock up happened while the GUI upgrade-everything-to-
latest tool was running.
When I power cycled the box to recover, the system was unusable -
flashing "system problem detected" popups, none staying stable long
enough to respond.
ssh + "sudo apt-get update" + "sudo apt-get upgrade" pointed me to "sudo
dpkg --configure -a"
That command reported numerous errors - I don't know which of them are
"normal" for this system, but hidden by the GUI, and which are new.
But it got the system semi-usable from the GUI, so now I'm clicking on
"yes, report it" for the many pop-ups, of which this is one.
FWIW, grub2-common is one of the ones "dpkg --reconfigure -a" complained
about.
