I feel I'm a bit out of steam, but the project I posted a month ago:

https://alexpdp7.github.io/selfhostwatch/

Is now IMHO in a useful state. It scrapes daily updates for "official" updates of stuff such as Nextcloud and the corresponding updates from Nextcloud. So you can see how dilligently YunoHost updates packages.

I feel YunoHost and similar stuff are great, but I feel it's daunting to commit to using them if you don't know how they handle updates.
