In case it's useful, let me document with more detail my issues when I try to follow the tutorial in https://doc.sagemath.org/html/en/developer/portability_testing.html#generating-dockerfiles as close as possible with 9.5 head

a. missing libgap-dev: because of build/pkgs/gap/distros/debian.txt contains libgap-dev the Dockerfile wants to apt-get libgap-dev which doesn't exist in the current ubuntu:latest. Seems related to #31534.

b. After working around that one (e.g. remove build/pkgs/gap/distros/debian.txt) the docker build command still builds the whole of sage because of the last step is "make ptest". It seems one needs to also add --build-arg TARGETS_OPTIONAL=ratpoints to avoid this.
