>What you expected to happen
Running `apt upgrade` would complete without issue.
>What happened instead
System hard lock, becomes completely unresponsive both from the local
terminal and over established SSH. Eventually memory is exhausted and
the machine reboots.
Upon restart, running `apt upgrade` returns the error: "E: dpkg was
interrupted, you must manually run 'dpkg --configure -a' to correct
the problem."
Running `dpkg --configure -a` attempts to complete installation of
shim-signed, segfaults, requiring a cold boot.
Only a fraction of the errors generated get written to the logs before
the crash as the crash prevents a final flush to disk. From a remote
machine I tailed several logs and triggered the crash again, then
copied the results from the terminal and attached to report.
