The first scheduled deploy failed on london-b because GitHub's gh apt
signing key expired on 2026-09-05. The common role now refreshes the
keyring from upstream wherever the github-cli repo is configured.
The proxmox_ve role was still writing a bookworm no-subscription source
onto hosts that are now trixie / PVE 9. I've switched it to a deb822
proxmox.sources using the host's release, and it cleans up the old
.list plus the enterprise repos in both formats.
