[ENH] - Upcoming: Ubuntu ≥ 23.04 (lunar) has user with UID 1000

[benz0li]

What docker image(s) is this feature applicable to?

base-notebook

What changes are you proposing?

This feature applies to image docker-stacks-foundation as soon as ubuntu:24.04 is used as base image.

Proposal: Delete user with UID 1000 before https://github.com/jupyter/docker-stacks/blob/main/docker-stacks-foundation/Dockerfile#L70:

if $(grep -q 1000 /etc/passwd); then \
  userdel -r $(id -un 1000); \
fi && \

How does this affect the user?

This feature ensures that docker-stacks-foundation successfully builds with upcoming ubuntu:24.04.

Anything else?

docker run --rm -ti ubuntu:lunar cat /etc/passwd

@mathbunnyru This can already be added preventively.

Thank you, @benz0li!

We have more than a year before the ubuntu 24.04 release.
I suggest we wait because I think this might change before release, and we might not have this problem.

I don't like adding such a fix preventively, especially this early.
At the same time, I agree this is gonna be an issue if nothing changes and I think the fix you suggest is reasonable (though we might want to remove homedir as well).

Good point. This might change indeed.

[...] (though we might want to remove homedir as well).

True. I have updated the command.

Closed for now. I set a reminder for early 2024 😬.
