Installing libsdl2-dev:i386 on image 20260309.50.1 fails

[tannewt]

Description

I'm trying to install libsdl2-dev:i386 in our github action so that we can build a 32-bit binary that links to libsdl2 but it fails on the new 20260309.50.1 image with:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libglib2.0-dev:i386 : Depends: libglib2.0-dev-bin:i386 (= 2.80.0-6ubuntu3.8)

E: Unable to correct problems, you have held broken packages.

This does work on the 20260302.42.1 image.

Hello @tannewt,
We were unable to reproduce this issue using the base image. However, I noticed that your PR removes Python (sudo apt-get remove -y python3 python3-minimal || true), which may be causing this issue.
Please try reverting or fixing that change.

I reproduced it here in an empty repository: https://github.com/tannewt/gha-test/actions/runs/23153965435/job/67263387097

This just has the repro steps from above, no python removal (that was added to try and fix the problem).

Thanks for looking into this!
