=== SUMMARY ===
Version 19.10
Packages built on Ubuntu Jammy 22.04 or later use dpkg-* versions that build the tarballs within the deb package with zst format compression, rather than xz. When the reprepro tool attempts to add the package to the pocket, it fails because it is unable to detect the control tarball with this new format. We found this out by conducting an strace of the action, since the package uploads showed as successful everywhere, but were silently (expect for an empty email) failing to add the package to the pocket.
=== WORKAROUND ===
None.
There is a way to specify compression format when building the deb, for example:
dpkg-buildpackage --compression=xz -B --sign-key=upload-key
However this does not seem to work and still creates tarballs with zst format.
