Hi,
Right now the unit tests from kpackage master branch are failing for me.
I suspect this commit:
https://cgit.kde.org/kpackage.git/commit/?id=af8721a5ccca9629ee4ffb884ac7ab5b633aabff
broke the autotests, my guess is that along with that change the unit tests test data should have been updated to also include the donation url.
Regards.
