This latest 5.8 update has caused a lot of issues for a lot of people.
The most critical being breaking:
Graphics Drivers
Virtualbox no longer working. You can fix this by downloading straight from
virtualbox.org but then that breaks Python.
WIFI Stops working

So perhaps not something I have done.
OTOH not something that should happen to a LTS version!!
