I have used the following instructions:
# yum -y update # yum install preupgrade # preupgrade-cli # reboot
It could not upgrade grub and after a reboot its still Fedora 10. The problem seems to be slicehost specific. Can you help me?
The steps are a little tricky to get from Fedora 10 to Fedora 11 on a Xen VPS. You might want to try this method instead.
Have you switched to the Fedora 11 Repos? What exactly have you done?
Have you followed these instructions?
