Mettre à jour manuellement Discourse et l'image Docker vers la dernière version

[JammyDodger]

The guides are reviewed and updated fairly frequently (this one looks like it had a little tweak in February).

The only one in there that I’m not personally familiar with is the docker one:

@sam

Due to the way docker packaging has changed you may also have to update your docker from lxc-docker or docker-engine packages. One way to do that is via the Docker script here (it will warn about an existing install but should upgrade ok):

wget -qO- https://get.docker.com/ | sh

This will now use the docker-ce main versions.

This is completely safe, we have never seen anything get broken by base Ubuntu updates.

But I can vouch for the accuracy of the rest.
