PackageKit error: downloadSubjectPublicKey?username=openhab is not a public key

I'm observing that cockpit on FedoraServer 33 is not able to show available package updates due to the following error:

downloadSubjectPublicKey?username=openhab is not a public key

The problem seems to be in the URL which contains question mark but it is not quoted. The following change fixes the problem:

# diff -u /etc/yum.repos.d/openhab-stable.repo.orig /etc/yum.repos.d/openhab-stable.repo

However, I'm not aware who is responsible for generating the openhab-stable.repo file.

Good catch @dwrobel, thanks for sending the PR on the Docs too!

One thing I'd like to do is include the .repo file within the package, so will remember this for next time. :)
