Comment 4 Thomas Haller 2022-01-17 15:52:17 UTC 
this is already fixed by https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/9a76b07f744201f1a94c95a40d7493927283ff7e
and thus a duplicate of bug 2026288


I probably will still post a follow-up patch, but in any case, this is a duplicate. Closing.
