Fixing my problem of a stuck 'dnf updateinfo info' on Fedora Linux
I apply Fedora updates only by hand, and as part of this I like to look at what 'dnf updateinfo info' will tell me about why they're being done. For some time, there's been an issue on my work desktop where 'dnf updateinfo info' would report on updates that I'd already applied, often drowning out information about the updates that I hadn't. This was a bit frustrating, because my home Fedora machine didn't do this but I couldn't spot anything obviously wrong (and at various times I'd cleaned all of the DNF caches that I could find).
