## The problem
Issue puppetlabs/puppet#9149 (closed, 7 comments): Debian 12 shipped with only Puppet 7 from Debian's own repos, and there were no official Puppet 8 agent/server packages on apt.puppetlabs.com. Nightly bookworm builds appeared first, then official packages landed with the 7.29.0 and 8.5.0 releases. Server, db, bolt, and pdk ship on separate schedules from the agent.
## What fixed it
Debian 12 support in the official Puppet APT repos arrived with the 7.29.0 and 8.5.0 releases; before that only the nightlies repo had bookworm builds. If apt.puppetlabs.com still lacks bookworm for the component you need, check the nightlies repo or the release notes for that specific package, since puppetserver, puppetdb, bolt, and pdk each release on their own schedule.
