I have a little more insights to provide - I realized that the server is on Debian 11 (Bullseye), which from what I’m reading isn’t fully supported yet. I’m guessing this is why I’m running into issues.

Is there a way to keep Debian 11 and upgrade Yunohost, either to 4.3.6.3 or to this [beta version](https://forum.yunohost.org/t/beta-stage-testing-for-yunohost-11-0-bullseye-and-buster-bullseye-migration/18531)?
