Using preupgrade to go from F14 to F16

[Isaac1357]

Using preupgrade to go from F14 to F16 I ran into two stumbling blocks after it rebooted when the upgrade was finished.

The first was that it was still using the F14 grub bootloader and booting with the F14 kernel.
This was solved by doing a "grub2-install <bootdevice>". Which in my case was "grub2-install /dev/sda"

The second was that I kept getting put into fallback mode in Gnome3. I tried both the open source and binary Nvidia drivers to no avail. I finally found an error in ~/.xsession-errors stating that the gnome-shell component was not found. Upon checking, sure enough, gnome-shell didn't get installed by the upgrade. A "yum install gnome-shell" and log out/in, and it was working properly.

Just throwing this out there for anyone else who may have the same problems w/ preupgrade, and out of curiosity to see if anyone else has upgraded this way and experienced the same.

That's pretty much normal. Upgrade doesn't attempt to apply new default package sets.

Thanks for your reply

Good to see they're working on the first one, I was planning on searching for a bug on that and reporting if there wasn't one, but was procrastinating because redhat/fedora bugzilla is sooooooo sllloooowwww heh

Yeah, I understand about the package sets thing, but I figured that in this particular case they may make the upgrade do it since they're completely replacing gnome 2 with gnome 3, rather than just updating to a new version of gnome 2. Either way it's an easy fix. I just wanted to get it out there in case anyone experiences the same problem and comes searching

Adam, I tried to post this in the bug report you listed above, but I can't remember my login for Bugzilla.

Anyway, I experienced the grub issue attempting to upgrade from 15 to 16 using Preupgrade. After finding this thread, I restored F15 using Clonezilla and tried again with the new Preupgrade RPM.

This time, Grub 2 was successfully installed and I could boot into F16 using the correct kernel.

However, Grub 2 was installed to the MBR rather than where it was originally located - in /dev/sda6 where my F15 installation was. Now I'm left with having to restore Grub to the MBR from my Arch install.

I really think this should be rectified before F16 is made gold. Grub 2 should replace legacy grub, but it should be written to the partition where legacy grub was, not automatically to the MBR.
