Following with solutions to many of these issues...
I'm using fedup to upgrade from fedora20 to fedora21 before going
fedora22, and there appears to be a few packages that have no fedora21
Packages without updates:
All of these were safely deleted without issue.
On another system, I have the following failure during fedup:
# fedup --network 21 --product=server
setting up repos...
fedora/21/x86_64 | 3.8 kB 00:00:00
fedora/21/x86_64/group_gz | 232 kB 00:00:00
fedora/21/x86_64/primary_db | 17 MB 00:00:23
No upgrade available for the following repos: updates
Error: can't get boot images.
The installation repo isn't currently available.
Try again later, or specify a repo using --instrepo.
I've searched quite a bit online, and all references to this issue
appear to be with much older upgrades. Any ideas would sure be appreciated.
This turned out to be a mirror issue. Somehow even after rebooting it
still picked the same mirror that was having a problem. I edited the
fedora-updates.repo file and hardcoded an IP address for one of the
mirrors that I knew was working properly.
