Update images to Ubuntu 24.04 LTS

[lukasbehammer]

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

docker-stacks-foundation

What change(s) are you proposing?

Use image ubuntu:24.04 to build from.

How does this affect the user?

Newer g++ versions higher than g++-11 can be installed via apt-get.

Anything else?

I develop a python package which uses C++20. To test the package before publishing I want to install it in a JupyterHub (Z2JH) instance. Since libraries that are not included with g++-11 are used, I want to use a newer Ubuntu version to be able to use g++-13. Changing the base image to ubuntu:24.04 fails because Ubuntu uses UID 1000 for the standard user "ubuntu" since Ubuntu 23.04. With the workaround under https://bugs.launchpad.net/cloud-images/+bug/2005129 (Adding "RUN userdel -r ubuntu" after the FROM statement to delete the user "ubuntu") I was able to successfully build a minimal-notebook image myself using ubuntu:24:04, installing g++-13 and finally build and install my Python package.

I think you can install gcc-13 on Ubuntu 22.04: https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test?field.series_filter=jammy
And it will probably provide g++-13 for you.

Please, close this issue if it works for you, as you have a specific gcc issue.

I also doubt we will be updating Ubuntu version any time soon:

1. We have a policy where we wait for the first point release: https://jupyter-docker-stacks.readthedocs.io/en/latest/maintaining/tasks.html#updating-the-ubuntu-base-image
2. We need to give developers and maintainers some time to update their software to be used on Ubuntu 24.04

Thanks for your fast answer. I will keep using my custom built image until you support a newer version.

Is there a timeline to update docker-stacks-foundation to 24.04? It is now the latest supported LTS.
