Receiving many "missing required part in given .deb" errors when syncing Ubuntu 22.04 repositories

Problem description

I receive the following error many times when trying to sync repository packages for Ubuntu 22.04, with only a fraction of the packages being linked properly:

2022/05/23 21:21:11 -05:00 missing required part in given .deb (expected one of: ['control.tar.gz', 'control.tar.bz2', 'control.tar.xz', 'control.tar.lzma', 'control.tar'])

@tlivolsi this looks like they used again a different compression algorithm inside of there debian packages.
Can you find out what they use?

[mcalmer]

Seems they use now control.tar.zst

This error message is coming from python3-debian package (which is used for reading the headers of DEB packages).

We currently used version 0.1.31 coming from Leap, we would need to update this to newer versions (latest is 0.1.44).

Apparentely, latest version comes with support for zstd: https://salsa.debian.org/python-debian-team/python-debian/-/blob/master/debian/changelog

[mcalmer]

We need to remember that the package needs to add Requires: zstd . They use the commandline tool to uncompress things.

The package is coming from the SUSE Package Hub 15 SP3 repository. There is no package for SP4 yet and I guess SLES15 SP4 may be released next month. So maybe this is the chance to create a new version of the package for SP4 and backport the changes to SP3

The update to python-debian to 0.1.44 fixes reposync. I did a SR that should go to openSUSE:Factory soon (https://build.opensuse.org/request/show/985321)

However the backport to SLE (and openSUSE) is a different story. I am quite sure we'll be able to have it only at SP4, because the 0.1.44 does not support Debian anymore. The internal ECO will handle this.

But in the end, for Uyuni, having the package at SP4 is enough (so openSUSE Leap 15.4 can get it).

Ths at my test instance, with the code from your PR @mayrstefan :-)

[juliogonzalez]

The update is now released, so I am going to close the issue:

$ rpm -q --changelog python3-python-debian|grep zstd
  * Add support for zstd compression in .deb files
  * Update packaging for zstd compressed .deb code

The support for Ubuntu 22.04 is not at Uyuni 2022.06, but it will be part of the upcoming 2022.07.
