In /var/univention/buildsystem2/apt/ucs_5.2-0/amd64/Packages{,.gz} we currently have two versions of the package xserver-xorg-core-udeb listed: Package: xserver-xorg-core-udeb Architecture: amd64 Version: 2:21.1.7-3+deb12u5 [...] Depends: [...], libudev1-udeb (>= 252.21), [...] Package: xserver-xorg-core-udeb Architecture: amd64 Version: 2:21.1.7-3+deb12u7 Depends: [...], libudev1-udeb (>= 252.23), [...] The dvd tests in jenkins show that the latter is not installable, because bookworm currently only has libudev1-udeb (252.22-1~deb12u1). This breaks the dvd iso creation. https://packages.debian.org/bookworm/libudev1-udeb Looks like a package dependency issue upstream, but it's also curious that the apt/ucs_5.2-0/amd64/Packages* files list both versions.

apt/*/ may have multiple versions of a source/package only after importing some new packages; that might happen when you use `repo-copy-dsc` to copy a single Debian package or use `~phahn/REPOS/toolshed/REPO/repo-copy-scope` to copy back the released errata. Afterwards you MUST 1. run `repo-apt-ftparchive` to re-create the Packages/Sources files to include ALL files 2. run `repo-apt-dedeup -s [-d]` to then delete the old packages `repo-debmirror` already runs `repo-apt-ftparchive` internally, but NOT 2. — you have to do that on your own. Why: Because `repo-apt-dedup` deletes files and it might delete multiple GiB if things go wrong; therefore it is not invoked automatically but requires running it manually.
Philipp also explained: The source package https://tracker.debian.org/pkg/systemd is from "stable-proposed-updates", not yet released as part of Debian stable. It should get released in something like ~1W as 12.6. xserver-xorg ( https://tracker.debian.org/pkg/xorg-server ) is also in stable-p-u, but already released as part of "stable-security" (stable-sec) and so it's already public. Since the Debian project builds ISOs only for releases, it's okay for Debian, to release the µDeb (udeb) already earlier and delay the update of systemd till the next PU, it's enough to reach consistency at that point.
