Hi ! We are using Discourse on community.museomix.org since many years But I encounter a strange problem when I rebuild the container, it fails with this message: undefined method `deprecated?' for nil:NilClass Here is the full rebuild discourse-doctor output if it can help DISCOURSE DOCTOR Fr…

You are running Discourse on a end of life Ubuntu version. You need to move to an up to date Linux install. That kernel version is way too old.

I’m on Ubuntu 22.04 LTS so not really end-of-life version but it seems I have a 3.x kernel
