Pipeline suddenly has started failing (Again)

It used to work flawlessly before, but now I keep getting:

$ apk --no-cache add py2-pip python-dev
fetch http://dl-cdn.alpinelinux.org/alpine/v3.12/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.12/community/x86_64/APKINDEX.tar.gz
ERROR: unsatisfiable constraints:
  py2-pip (missing):
    required by: world[py2-pip]
  python-dev (missing):
    required by: world[python-dev]
ERROR: Job failed: exit code 2

Any pointers about whatever new gitlab changes that are breaking the pipeline?
