Perhaps Kexec allows to full-upgrade the live media and test, if the new
kernel suffers from a regression.

Upgrading and installing works when running Ubuntu from a live media,
it's just not possible to reboot. Logging out and in and restarting
services works, too.
Testing the new kernel using the live media, IOW without rebooting,
might work when using Kexec.
