I preupgraded my system to F14 (just before the release of the beta)
and it seemed to run fine.
But a quick check up after the upgrade showed me that something went wrong as yum in particular doesn't run anymore...
# yum update
Traceback (most recent call last):
File "/usr/bin/yum", line 28, in <module>
ImportError: No module named yummain
So I tried to boot to the rescue mode with the boot.iso but found that it didn't have yum included.
So what do you think is the best way to repair this system ?
