I'm more than willing to bet this is a Python 3.10 compatibility issue, which means it's 100% upstream.

Looks like it was fixed (https://gitlab.gnome.org/GNOME/pitivi/-/issues/2571), but no release.

[Erich Eickmeyer (eeickmeyer)]

This should do the trick.

[Erich Eickmeyer (eeickmeyer)]

Fabio,

Try installing the pitivi package in https://launchpad.net/~eeickmeyer/+archive/ubuntu/ppa2 and see if that fixes this problem. If you can confirm that the problem is fixed there, I can upload this to Jammy.

[Erich Eickmeyer (eeickmeyer)]

Nevermind, found some time to verify it myself. :)

[Launchpad Janitor (janitor)]

This bug was fixed in the package pitivi - 2021.05-1ubuntu1

---------------
pitivi (2021.05-1ubuntu1) jammy; urgency=medium

  * Patch to update collections import in Python 3.10 (LP: #1963800)
