OK thanks!

I checked on my system:

apt policy linux-image-generic-hwe-20.04
linux-image-generic-hwe-20.04:
  Installed: (none)
  Candidate: 5.15.0.126.136~20.04.1

So I used the server install line for 20.04 LTS:

sudo apt-get install --install-recommends linux-generic-hwe-20.04

There were a number of warnings

Warning: The home dir /var/lib/usbmux you specified can't be accessed: No such

But it reacheda done final stage....

And now I have:

$ uname -r
5.4.0-89-generic

dpkg --list 'linux-image*' | grep ^ii

Do I have to reboot to finalize this kernel upgrade?


If so I have a window between 8 and 11 tomorrow mmorning when the server is not
scheduled for anything important.
