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?
Have you switched to the Fedora 11 Repos? What exactly have you done?
Have you followed these instructions?
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.
