I've seen this the last couple of days.
I tried "dnf clean all" so I'm hoping it's not only me that is seeing
it.
$ sudo dnf check-update

Cannot download, all mirrors were already tried without success, disabling.
I also suspect the most recent updates broke my nm vpnc connections.
NetworkManager[1037]: <error> [1447107345.368818]
[vpn-manager/nm-vpn-connection.c:1980] get_secrets_cb(): Failed to request VPN secrets #3:

Worked the day before (I use it every day) but not since.
Hoping these are known issues.
Cheers,
