This should be resolved now, but the changes will need a few hours to propagate :-)
(so, it may take up to six hours for the data to become visible, subsequent updates will be much faster)

Thank you for the issue report! This problem should be resolved with the latest updates :-)

Should be fixed in a few hours :-)

This is an annoying issue, as it is extremely hard (if not impossible currently) to fix properly. A proper fix would be to re-sign the fwupd-amd64-signed binary package, but we can not do that as we do not have any EFI signing facilities for PureOS...
This package has been removed from PureOS (as we don't support UEFI with secure boot signing enabled properly anyways), but users who have installed the package manually before will of course run into this issue now until they run an apt purge fwupd-amd64-signed. We could force the removal of this package via conflicts, but that may also not be an ideal solution here :-/

This is resolved now - please test the images available on https://downloads.pureos.net/byzantium/ (preferably the latest ones built ^^) as I could only test this on a few systems and configurations that I had available. The images should support UEFI, as long as secure boot is not enforced, as the necessary pieces are not signed.

We certainly can't update the system's certificates store, as that would mean people couldn't get the update that lets them get updates again :-P

This should be resolved in byzantium already :-)

Does this issue still exist? I changed the image build process quite a bit, so the current images are not comparable to the old ones.

This should be fixed in landing/byzantium for a while now :-)

I would rather add a search function to this, as this page can get extremely large (to the point of hanging up a browser tab).
Currently, the database has indices (no dedicated fulltext searches), but with that one could already implement a simple search. Added to the todo list, but as usual, patches welcome :-)

Just FTR, we can't binary-sync anything from experimental, ever. Packages there are built with other binaries from experimental, which would break any suite we sync them into. Source syncs can work though, but will need support implemented in Synchrontron in Laniakea.

To me, this Lintian check actually makes little sense. The one for Maintainer is important, so the maintenance status is reflected in the modified package, but Changed-by could be any address. When Zlatan and I created the project, the initial goal was explicitly to get the community involved and have people outside of Purism contribute. That didn't really work out, but by limiting change authors to people with an @puri.sm address we make this even less likely and also make the project look a lot more like a Purism inside job than is good for it ;-)

This was a bit tricky, as byzantium is still an in-development release and all changes should go through landing. Fortunately though, the synchrotron Laniakea module is flexible enough nowadays to accommodate for that.
I've implemented a solution which will fill up the -updates and -security suites directly for byzantium from the respective bullseye suites, while not allowing manual uploads from us which should still go through landing. That workflow should work well for byzantiums current odd in-between state between "released" and "in-development".

We could probably have debug symbols packages for our self-built packages with a bit more space (the dbgsym packages are *insanely* huge, they dwarf the size of the actual archive), but for the full archive, so syncing the debug symbols from Debian to make them available easily in PureOS, we'd need quite a lot of space (I need to look at Debian to actually give a - then very good - estimate).
At time, PureOS holds dbgsym packages for everything that we have built in the landing suite, but byzantium doesn't have own debug symbols. You can however use the ones from landing, which are either equal to the versions in byzantium, or newer.
