for non irc/matrix users, I've written a patch, found in draft PR #3898

It may solve the issue but I'd like to get testing before thinking about getting the PR merged. So, feedback welcome

Hi!
I had the exact same problem with the podman driver and I "resolved" this by not installing molecule-podman but only molecule-plugins, see https://github.com/fauust/ansible-role-mariadb/pull/35/files#diff-4d7c51b1efe9043e44439a949dfd92e5827321b34082903477fd04876edb7552.

But I am not sure what's going on, also I did not had the problem with python3.9 (only with python3.10 and python3.11).

[apatard]

@fauust yeah, I found out later that the error was also related to having the "old" plugin modules like molecule-podman or molecule-docker or molecule-vagrant. They should not be used any more and molecule-plugins should be used. Still, it's not fine to break systems for people having both installed. Unused code should not break things.

[fauust]

@apatard I could not agree more with you but I am kind of used that molecule release break stuff :)
Here is a documentation improvement suggestion #3899.

[fauust]

Seems like a duplicate of #3883.

[apatard]

The backtrace is different. While it's triggered by installing molecule[docker] instead of molecule-plugins[docker], molecule should catch this properly. IMHO, a backtrace due to missing driver should not exist and be fixed.
