I used NextCloud in a Docker container but found that unless I was really on top of checking versions for updates, it was very easy to get behind and then unless one way VERY careful about going up in the correct increments, it was quite easy to end up with a version mismatch between the files and DB structure.

As much as I hate SNAP (mainly due to them being overused on Ubuntu desktop and bloaty blobs full of weird permission issues) I’ve got to say that moving to a SNAP version of NextCloud on my server has made my life so much easier. A scheduled job runs a “snap refresh” regularly and it’s been fairly stable for over a year now, except for one small incident where it broke the reference to the internal office suite install and for some reason stated trying to go with a localhost version
