fedup leaves me stuck between 21 and 22

[sean darcy]

running updated 21.

fedup --network 22

Preparation seemed to go well:

........
[   191.911] (II) fedup:<module>() /usr/bin/fedup exiting cleanly at Tue 
Oct  6 12:26:25 2015

Rebooted.

Died somewhere in upgrading. Is there any log of the upgrade ?

No new kernel installed. Reboots into 21 kernel. Lots of dupes. yum 
upgrade just give 21 updates.

fedup no help:

fedup --network 22
usage: fedup <SOURCE> [options]
fedup: error: argument --network: version must be higher than 22

Any help appreciated.
