    This close to the freeze, we'll need test rebuild results. And note
    that the freeze is just around the corner, so please provide them
    quickly if you want to see this in trixie.

    I've managed to test build all packages against Qt 6.8.2 in
    experimental.

    * 3 packages (layer-shell-qt, libkscreen, plasma-workspace) produce
    symbol errors, but they are easily fixable once these packages have been built against Qt 6.8.2 in unstable.

    * pyside6 in unstable will highly likely fail to build against 6.8.2,
    but the version in experimental builds successfully against 6.8.2 and
    just needs to be uploaded simultaneously.

    * I could not verify nvidia-cuda-toolkit as I ran out of memory.

    The remaining packages all build successfully against Qt 6.8.2.

    It seems that QSignalSpy changed in QT 6.8 and therefore this breaks owncloud-client: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1100249

    And now I have to deal with that while upstream has not adapted to these
    6.8 latest changes.

    How did you make your rebuilds?

    We do not rebuild every package that uses Qt 6 in the transition, but
    only those packages that use the private headers since they do not
    provide a stable ABI or API.

    owncloud-client does not use the private headers which is why we did not rebuild it.

    However, it seems this issue with Qt 6.8 was identified and fixed
    upstream some time ago: https://github.com/owncloud/client/pull/11943

    You should be able to simply backport that.

    I would expect that you would test all things that build depends on qt when you do such a late transition especially when the changeset is not begnign.

    I'll create a patch.

    I'm sorry, but rebuilding all packages that depend on Qt is not doable
    with the resources that we have.

    I'm not sure why owncloud-client failed to build because AFAICS there
    was no API change. Who knows which detail changed somewhere in the Qt
    code. Maybe owncloud used it the wrong way and it just happened to work.
    I don't know.

    The changelog for 6.8 explicitly mentions the changes for QSignalSpy not inheriting from QObject anymore. This sounds a bit like an API change.

    Bests,
