Recent regression in dockerbuilder or gbp image

Hello!

I noticed yesterday that all of my MariaDB Gitlab-CI jobs started to fail. The gbp executes OK without errors but the job still returns an error code.

I fixed this by building older versions of the gbp and dockerbuilder images in my own repo: mariadb-team/mariadb-10.3@cdb4fb6b

You can see this demonstrated at https://salsa.debian.org/mariadb-team/mariadb-10.3/pipelines

Any ideas what regressed?

Something here?
