@lhotari 👋 since you noticed this issue 😄
while you're here, looks like we can't comment on your issue in github/virtual-environments. the way you phrased it made us initially think that only 20.04 was affected, but visibly it is also affecting 18.04. It would be interesting to mention that in your issue 🙇

since we've determined that 18.04 is also affected, might as well use if: startsWith(matrix.os, 'ubuntu-') wdyt?

Hi @simonbasle and @violetagg , nice to meet again. :)

The problem is that I'm not able to comment on the issue or edit the description (GitHub App showed the abilitity to edit the title, but it returned "permission denied"). I guess the only way to communicate with the maintainers is to create new issues.

I added more information to the GitHub community discussion where the problem was reported. I mentioned that ubuntu-18.04 is also impacted (and possibly other VM types). Feel free to add more comments to the GitHub community discussion.

Ah bummer! Thanks for trying, and for reporting that in the community discussion @lhotari 👍
