Since about a week I have trouble synchronizing with the VirtualBox repository. All other Fedora repositories work fine. I have copied once again the repo file from the VirtualBox website and imported the corresponding key, but to no avail:
I also tried to clean up the dnf cache with "dnf clean all", but that did also not help.# dnf update
...
Failed to synchronize cache for repo 'virtualbox', disabling.
...
Is there a problem with the servers at Oracle?
