A re-run didn't succeed.

I'm getting this issue as well in another repo that uses WSL in Azure DevOps hosted agents, it used to work properly about a month ago. Did you find anything that could work around it? Thanks!

[joshmouch]

It may be completely unrelated, but I got this "adduser:..." error when I did an "Enter-PSSession" to a server to install a disto instead of "ssh" to the server. The difference may have been that the first used an Active Directory admin and the later used a local machine admin account.
