Upgrade fails (Fedora 12 to Fedora 13)

kuwaitikid · 03-29-2011, 09:36 PM

Hi,

I am trying to upgrade from Fedora 12 to Fedora 13 using "Preupgrade" but it fails in the last part and tells me that the system cannot find the previous system (fedora 12). I have tried to do the upgrade several times and always the error is the same. Any help to fix this would be much appreciated. Thank you

Your best bet is probably:

1. Make sure you have a good backup
2. Get the Fedora 14 DVD
3. Upgrade directly from FC12 => FC14

PS:
I'd strongly urge you to use the DVD!
And not mess around with FC13, unless you absolutely have to.

I would not advise to use the upgrade path (pre-upgrade, etc ...).
Every time I've tried it, I ended up with an unstable system.
I would backup my personal data to an external disk (full home directory, /home/myaccount)
install from scratch Fedora 14
get your personal data back (not the full /home/myaccount directory because I don't trust fedora 12 preferences to be good enough for fedora 14)
then get just a few preferences files that you don't want to redo manually (networkmanager wifi keys for example).

Personally, I run Fedora 13, and I'll wait for fedora 15 at end of May

I've used Preupgrade exclusively from every version of Fedora since Fedora 8 to Fedora 14 without issue. I can tell you that having /home on a separate partition at least for me, didn't cause a problem

But yes, clean DVD install would probably be the way to go if there are issues. I did get a problem at work where using Preupgrade from Fedora 13 -> Fedora 14 sometimes crapped out with "couldn't find root file system" error. But this didn't seem to be consistent and several retries later, it worked.
