Upgrade: Nextcloud version to latest LTS version (from 28 to 31)
Our current Docker composition (based on linuxserver.io) is:
nextcloud-webapp:
image: lscr.io/linuxserver/nextcloud:28.0.2-ls300
LinuxServer.io offers these Nextcloud images
- Circa 2025-Q3, their 'latest' version is:
31.0.8-ls392
...which leads to the question: "If we wanted to apply incremental image upgrades, how many would we need"?
Surveying the release logs from Nextcloud:
$ curl -s https://nextcloud.com/changelog/ | awk '/Version / {print $2}' | head -n 55...shows that:
- We are 55 releases behind. Yikes!
That's a lot of sequential upgrades, if we want to do things in a... ummmm... "safe" manner.
But hey! This is an experimental instance. And we gots no "real" user data yet.
So....
We're going to try upgrading directly to nextcloud:31.0.8-ls392
Note that we will not configure our image spec to be: nextcloud:latest

That didn't work.
Our URL (served via a reverse proxy from Nginx Proxy Manager) gave us an error: "502 Bad Gateway".
