F12 to f15 stalls at re-boot using PreUpgrade

ColinA · #1 26th May 2011, 02:14 PM

Hi all.
I am trying to upgrade my F12 system ti F15 using the PreUgrade route. The initial package download goes Ok but on re-boot I can only access my old F12 system. df reports 44M avail in /boot which is on sdd1. Since I do have a multiboot system I checked that there was an "update" folder under "boot" and that it had the update versions of vmlinuz and initrd which it had. I edited "menu 1st" as described in the Pre-Upgrade notes setting the root entry to (hd0,0) as used for my working system and then did a re-boot. I selected the new upgrade entry in the GRUB menu but the system complained that it couldn't find a file. I have tried using root (hd3,0) but this does not work either. What am I doing wrong?

Preupgrade was never to skip releases in between. There are too many tweaks and alterations that just don't happen when skipping versions.

Your best bet is to boot a recovery CD and backup your non-system files and reinstall.

Hi. J.Pollard.
The "How to use PreUpgrade " document specifically states that it can be used to go directly to the latest version without going through intermediate ones. It did not balk at my original request to upgrade from F12 TO F15. Maybe they are telling Porkies!
Cheers Colin

Does the live version work for you? It would make sure of compatibility, though I don't think there should be any.

preupgrade makes a lot of assumptions - amount of free space in /boot for one. It needs 600MB or more, though 400 is listed as sufficient, there have been problems upgrading at 400. The limit may be determined based on added packages (above and beyond the base) as to how much it needs.

Another limit is that of 1GB of memory. Yes it will run at that, but during an upgrade it just might need more.

Instead go for F14. You may get problem with python because in F13 or else there was an experiment about python 3.0!

I am looking forward to preupgrade from F13 to F15, will it create any problem?

Hi all.
I am rather puzzled as I seem to have the two files referred to in the GRUB script but keep getting "Error 15 file not found".
vmlinuz (3.6MB) and initrd (93.7MB) are in /boot/upgrade as seems to be expected. Is it these the system can't find or a file they try to run?

There is also "ks.cfg" file which is shown below. The UUID seems to equate to /dev/dm-0 whereas my boot device is /dev/sdd1 UUID=77fc2d77-af8c-411f-9533-a4d2cf0216c6

# ks.cfg generated by preupgrade

reboot

%post
grubby --remove-kernel=/boot/upgrade/vmlinuz
rm -rf /boot/upgrade /var/cache/yum/preupgrade*
%end

I will try the live version of F15 later today if possible as I need to download it. Later--------F12 Live KDE tested and seems to work fineon my hardware.

Further information.
Although PreUpgrade has added an "upgrade" folder with update versions of vmlinuz and initrd to /boot and I can see them via Dolphin I cannot find that upgrade folder using "Find Files". Find Files can find other folders in /boot (eg efi and grub). Also I cannot add another folder to "upgrade" using Dolphin, as the option is greyed out. This may explain why the grub script cannot find the files either. I have tried changing the permissions on "upgrade" and this did not help and I am running as SU anyway! Is there a VERY hidden file facility in operation?
