Adding / Removing Domains raises an error

Describe your issue

Hello,
I wanted to create a new domain via the WebGUI and got an error (see below).
It was still working until yesterday. In the meantime, I updated YNH from .29 to .32. Could that be related?

I also just noticed that deleting a domain also aborts with an error.

Is there anything I can do myself? If so, what?

Logs are in https://paste.yunohost.org/raw/ledafusoka

And these are displayed directly in a popup-layer in the webgui:

Hmmm I don’t have time right now to work on a fix, not even a workaround, but that sounds related to a bug in the core in combination with mailman3 ..

[Aleks]

Or maybe just try to

sudo rm -rf /var/cache/yunohost/regenconf/pending/postfix_mailman3

though not sure why it would remain on the disk somehow

[tinder]

Hey @Aleks thanks for your tip. It seems to have helped. I can now create domains again. MailMan3 also seems to be working. In any case, I was able to send an email via my test mailing list.

[tinder]

@Aleks Okay, that’ll do for now. I hope there aren’t any hidden surprises waiting for me. Then you’ll have some breathing space, and it’s not an emergency for most others if it’s only relevant for individual users with MailMan3.
