Status changed to 'Confirmed' because the bug affects multiple users.

[Thomas Battermann (t-battermann)]

Tried to update Ubuntu running on Windows Subsystem for Linux (WSL) from 18.04 to 20.04.

I have what I believe to be the same problem upgrading to 20.04 with do-release-upgrade.

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libc-bin : Depends: libc6 (< 2.28) but 2.31-0ubuntu9 is installed
 locales : Depends: libc-bin (> 2.31) but 2.27-3ubuntu1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

affects me too, I tried to upgrade WSL 1 from 19.10 to 20.04 with do-release-upgrade

[Alexander Lehmann (a-lehm)]

This is a bug (or rather a missing feature) in WSL, see here: https://github.com/microsoft/WSL/issues/4898
