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.
