I can reproduce the issue on when trying to upgrade from Ubuntu 20.04.2 LTS to Ubuntu 21.04 using `do-release-upgrade` on WSL 2.
I don't get any real error output. The last this I see is a screen that shows only: Reading cache Checking package manager Reading package lists... Done Building dependency tree Reading state information...
