Preupgrade - the root for the previously installed system was not found

[alexuk]

After several problems I eventually managed to tweak /boot to make more space, cleared up /var/cache/yum etc and preupgrade dowloaded all pacakges. Upon rebooting I got:

"the root for the previously installed system was not found"

Upon exiting system rebooted in F11.

I tried clearing /var/cache/yum doing an yum update first, but still have the same problem. For some reason the new kernel cannot find the root anymore - could grub.conf be wrong?

Managed to take a look at the log.
I think the error is
"INFO: product Fedora version 12 found on <partition> is not upgradable".

Still no solution to this.

Hi all.

I have found the same problem when updating from F12 to F13.

The first upgrade failed due to the update of package squid.

After failure, I rebooted and reinstalled squid package manually.

When I tried to finish preupgrade, it showed the same message error:

"the root for the previously installed system was not found".

In anaconda logs, I saw the message:

"INFO: product Fedora version 13 found on <partition> is not upgradable".

It found an installation of F13 because file /etc/fedora-release had already been updated.

I changed that file to the F12 value, rebooted and... it worked!
Preupgrade finished and after reboot I changed back the release file.

I hope this workaround is useful for anybody.

Regards.
