I tried to fixup the patches from Andreas to use Python 3.6 in CentOS7
and force the new image build:
https://gitlab.com/samba-team/devel/samba/pipelines/59674602

The centos7 image build seems to succeed, but then the centos7-samba-o3
build does not start and only has:

ERROR: Preparation failed: invalid reference format (executor_docker.go:168:0s)
Will be retried in 3s ...
ERROR: Job failed (system failure): invalid reference format (executor_docker.go:168:0s)

Does that mean there is something wrong with the image or the tag?
