Dependency hell after upgrade to F18 from F17

view story

http://forums.fedoraforum.org – Upgraded from F17 to F18 just now using : fedoraproject.org/wiki/FedUp#Network Command I used: Code: sudo fedup --network 18 --debuglog fedupdebug.log --instrepo http://dl.fedoraproject.org/pub/alt/qa/fedup/f18-RC4/x86_64/ Upgrade went smoothly and everything works out the box, but I'm hitting with dependency issues when trying to install new stuff. Example (when trying to install apper after the upgrade) : pastebin.com/iCBWeyVP yum list extras with fc17 references : pastebin.com/y9UUR4C8 I seem to have similar questions to this thread : forums.fedoraforum.org/showthread.p (HowTos)
