Why is that? What is it trying to fix?

[J0WI]

same as #431

[nickvergessen]

The production live instance that produces https://docs.nextcloud.com/ is actually a Ubuntu 18.04
So for now I think we should not update this, so it does not get changed in a way that later on breaks production, but it was working in a random default docker on CI?

[J0WI]

That's odd, Ubuntu 18.04 is already EOL and the current CI image is based on 20.04.

[nickvergessen]

We are aware of this and will update the topic as soon as we have time for it and fixed production. Until then I would pause this here.

cc @tobiasKaminsky for sysadmin

Tracked it to update as soon as we have time.
18.0.4 LTS is still supported until end of year.

[J0WI]

I don't know your support license but this source says April 2023.

[J0WI]

There was an update of the base in 1cd1555 but meanwhile Bookworm was released

[nickvergessen]

Production is still using Ubuntu (22.04 by now), so would be cool to keep that. 🤷
