Bug 2374863

Description of problem:

```
When I run an offline update from KDE Discover on a fresh copy of Fedora KDE ARM64 on RPI4, I am unable to sucessfully update the system with the following error given to me after I reboot the system:

Failed to update 1 package
package mozilla-openh264-2.5.1-1.fc42.aarch64 cannot be verified and repo fedora-cisco-openh264 is GPG enabled: /var/cache/PackageKit/42/metadata/fedora-cisco-openh264-42-aarch64/packages/mozilla-openh264-2.5.1-1.fc42.aarch64.rpm could not be verified.

```

Running the following command to automatically sign the openh264 repo:
```sudo dnf config-manager setopt fedora-cisco-openh264.enabled=1```

Then re-running the offline update from Discover, I get a different error: 
```Failed to update 1 package
package aurorae-6.4.0-2.fc42.aarch64 cannot be verified and repo updates is GPG enabled: /var/cache/PackageKit/42/metadata/updates-42-aarch64/packages/aurorae-6.4.0-2.fc42.aarch64.rpm could not be verified.

This means something is going wrong with verifying packgers.
