Public bug reported:
Upon reading an Ubuntu page that said it was possible to upgrade my
Ubuntu-under-Windows 10 install (WSL) from 16.04 LTS just by running do-
release-upgrade, I excitedly went to my terminal and ran the command.
First it refused to run because system was not fully updated. Fine, I ran:
sudo apt update
sudo apt dist-upgrade
This process completed without any errors. I then ran do-release-upgrade
again. This time it started okay and got through most of the process.
But then at some point it decided to run grub even though I am running
Ubuntu under WSL, so presumably grub should not be used. It did
apparently detect that it wasn't needed, because it asked me if I was
sure I didn't want to install it on the boot device. I answered yes.
Then the install proceeded to LXD but soon after came an error related
to grub.
After that it went downhill fast with at least 2 other errors.
Additionally, when the system attempted to roll back the upgrade I got
an error from a kernel package.
