Thank you very much for your help, I really appreciate that.
Upgrade was not a trouble free task, I needed to manually download a couple files.
cat /etc/yum/vars/releasever gives "File not found", because that file doesn't exist.
Code:
[root@lpg-dell-fedora vars]# sudo yum info fedora-release

It seems the problem was caused by F16 fedora-release package. I uninstalled it and reinstalled F17 fedora-release. Now everything seems to be OK.
Thank you very much again.
