I noticed that when I clean dnf's metadata and then run dnf upgrade to fetch new metadata and check for upgradeable packages multiple times, it tends to often download different amounts of data which sometimes result in one run not having any updates while the next run might do.
How can I fix this and always get the freshest (i.e. newest) metadata in dnf on Fedora (26)?

That's not the problem. What I do is I remove all of the cached metadata via
dnf clean allbefore thednf upgradecommand. The problem is what it downloads as metadata differs in multiple runs of the two commands. – comfreak – 2017-08-11T13:54:29.437Well that shouldn't be possible - everything is checksummed and if you expire the cache it will refetch the root descriptor and then validate everything else against those checksums and refetch them if they are wrong. – TomH – 2017-08-11T16:38:42.373
It's probably hitting different mirrors, which may not all be synced to the latest updates. – mattdm – 2017-08-11T17:44:09.077
@mattdm That's my guess as well, but how do you fix that? Can I change it to their source directly? Or is the only option that I create my own mirror? – comfreak – 2017-08-11T18:23:52.190
Creating your own mirror is a decent option, or you can edit the
.repofiles to point at a specific mirror. If you have more than one system, creating your own mirror is likely the best choice. And please don't point at the main Fedora servers, because if everyone did that we'd be overwhelmed. Find a fast, nearby mirror and use that. – mattdm – 2017-08-11T18:31:42.520
