dnf system-upgrade error

[Richard Shaw]

Trying to update my f21 system to f22 but dnf system-upgrade is giving me
an error:

# dnf system-upgrade download --releasever 22

Using metadata from Fri Nov 13 07:54:36 2015 (3 days, 5:43:10 hours old)
Error: cannot install both nosync-1.0-2.fc22.x86_64 and
nosync-1.0-2.fc21.x86_64

Why would both need to be installed? Is it trying to tell me that even
after the proposed transaction that something would be requiring f21 nosync?

Thanks,
Richard
