DRIVER-NOT-CONNECTED

[Bob]

I have a UPS and have installed the NUT Monitor.  I have just noticed that it
has not been running for a while.  At startup the NUT window closed before I
could see any error messages so I started it from the command line.  I assume
the reason it stopped running is that a driver has not been installed after an
Ubuntu update.  Being a somewhat newbe to Ubuntu I had expected that an update
would not cause this kind of problem.

Do I need to uninstall the NUT Monitor and reinstall it or is there another way
to get the driver working?

Is there a way to tell when I need to do that after an update?
