@Krenair migrated the main puppet masters for Cloud VPS to Puppet 5 (thanks!) and these self-hosted puppet masters are still using Puppet 4 and will break when Puppet 5-specific code gets merged to puppet.git (or when code gets merged which is buggy with < 5).
They need to be replaced with an equivalent VM running Buster (as Puppet 5 packages are only available on Buster) or removed if obsolete.
