Fix ubuntu version in dockerfiles

[whamtet]

Thanks for the great work @cnuernber , I'm getting some issues when I try to build the images in in dockerfiles and it looks like its because you're starting FROM ubuntu:latest. Can you remember what version you were able to build it from and set the number accordingly? On my Intel Mac with Docker Desktop it hangs on step 3 asking for geographic information.

@behrica - What version of docker are you using when you build images?

[whamtet]

@cnuernber I think its the ubuntu version, not docker version. ubuntu:latest is not a fixed version so it has changed since the scripts were run successfully.

Right - sorry - my opinion is to upgrade to latest stable Ubuntu

Regarding the problem of "interactive" asking for something:

I have seen this from time to time, and there are usually specific command line options to prevent them.
But it is indeed a good idea to freeze teh ubuntu versions in

libpython-clj/dockerfiles/Py39Dockerfile

Line 2 in f146cbd

FROM ubuntu:latest

This make its more future proof.

I use various ubuntu versions, so I am not sure what is guaranteed to not have this problem.

The best thing would be to find a continously maintained Docker image which has python + Clojure preinstalled, and just refer to it.

The closetsI found was python + java:
https://github.com/jupyter/docker-stacks/blob/main/pyspark-notebook/Dockerfile

But is has a lot of other staff as well, so gets big.

an other pproach is to use "devcontainers".
This separates "base image" and "features added to it".
I made a working one here:
