[Bug 1956150] [NEW] System doesn't power off or restart after full upgrade

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

I did a clean install of Lubuntu 20.04.3 LTS on my system and I didn't
install any extra software after this install. Everything was working
just fine, my system would shutdown and restart normally. This morning,
after being prompted to do a full upgrade of the system, I did it. The
upgrade was successful and I was asked to restart my pc. After this
upgrade, when prompting my system to shutdown or restart, it just won't.
If I choose to shutdown, the screen goes blank but fans are still on and
so is the power led. To fully power off my system I have to perform a
hard reset by holding the power off button. The same thing happens when
trying to restart it.
