i was upgrading from fedora 8 to fedora 10 , but i earlier installed the packages from livna and freshrpm repo . so it was causing dependency problem in step no 2 . yum update .

so i had to exclude them

yum update --exclude=xine-lib

and then there were few warning regarding the dependecies in the preupgrade , but all ended well.

the most annoying thing was the slow download of the packages.

one more thing , i am not having the linux grub , instead of that i have solaris grub , so when it reboots , u wont find an option for the upgrade in the boot menu , all u have to do that , boot into soalris and read the grub entries from the linux grub.conf and update menu.lst , and now reboot and boot into the fedora upgrade. after the upgrade it will again reboot and now again u have to make new entries in the soalris grub.conf/ menu.lst .

u all at home :) . enjoy mighty fedora 10.
