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.
