Packages without updates during 20->21 upgrade

[Alex]

Hi,

I'm using fedup to upgrade from fedora20 to fedora21 before going to 
fedora22, and there appears to be a few packages that have no fedora21 
equivalent:

Packages without updates:
   aic94xx-firmware-30-6.fc20.noarch
   febootstrap-supermin-helper-3.21-2.fc18.x86_64
   gnupg-1.4.19-2.fc20.x86_64
   libgssglue-0.4-2.fc19.x86_64
   perl-PlRPC-0.2020-15.fc20.noarch
   prelink-0.5.0-1.fc20.x86_64
   1:anaconda-yum-plugins-1.0-10.fc20.noarch

The aic94xx I assume is for my Adaptec controller. No upgrade for gnupg? 
perl-PlRPC is for amavisd-new.

Is this something to be concerned with before proceeding?

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.

Thanks,
Alex
