I encountered an error Sunday night on 1 out of 6 systems, all updated
within the same 60 minute (or less) period. The one system gave a
segfault error at the end of the dnf update, and corrupted the rpm
database. After rebuilding the rpm database and re-running dnf udpate
it reported no errors and no further updates. System rebooted without
incident and I am not aware of any other related issues.
I realize this is not much help, but at least it is another data point.
