fedora-repos ships fedora-cisco-openh264.repo in the default install and the .repo file has skip_if_unavailable=False. However, the actual repodata the repo points to is missing. This causes packagekitd to legitimately error out, leading to nonworking software center in Fedora Workstation.

Please do one of the two: 1) Create empty repodata for the repo and sign it correctly. Having actual openh264 rpms is secondary, just having a dummy empty repodata would be OK for now. 2) Do a fedora-repos build that removes skip_if_unavailable=False from fedora-cisco-openh264.repo
The content has all been signed and shipped to cisco. rpms are now available from them
