Interested in opening a PR to fix?

[fabricepipart1a]

In theory yes. Practically, this is not a good opportunity because I am a Java developer with scripting capabilities (who did not get attracted each time he started reading some go). If you have hints how this should be fixed, you can share it here in case I have a colleague that wants to get started.

[yangboroy]

The same issue.

i have a fix for this , but it is somewhat layered.

[tnk4on]

There is a bug in the fix.
For default VM, podman machien ssh <command> will fail if podman-machine-default is not specified in VM name.
