upgrade from fedora 20 to fedora 21 failed!!!

mgrah · 11-23-2015, 06:37 AM

Hi there,
Need a help.
I tried to upgrade from fedora 20 to fedora 21 after reboot fedora 21 can't start. When trying to use the old kernel I got the same error. Can't launch fedora 20 neither.
I'm in grub but can't figure out how to fix the issue.

grub> ls
grub>(hd0) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1) (fd0)
when trying to set proper /boot
/grub2/locale/en.mo.gz

can some one help?

Thanks

You did not post whatever error you got, that would be a good starting point?

the thing is that I can't load fedora 21 after my upgrade.
I can access grub2
and even from there I tried solve and reboot, I get a kernel panic.
I can find some old kernel and some new one.
some error code:
error: file '/grub2/locale/en.mo.gz' not found.

BE WARNED!!!

Fedora 21 is not supported any longer
please do a clean fresh install with the current version
Fedora 23

Hello mgrah. You could try re-installing grub. Use the rescue option on the install disk. The commands you'll likely need are:

Code:

chroot /mnt/sysimage
grub2-install /dev/sda
grub2-mkconfig -o /boot/grub2/grub.cfg

Exit the chroot and reboot.

chroot /mnt/sysimage
chroot: cannot run command /bin/sh: No such file or directory

/mnt is a space separate from chroot !

Code:

chroot /mnt/sysimage

That looks very sick. How about

Code:

ls -F /mnt/sysimage
ls -F /mnt/sysimage/bin

Or perhaps not sick, and you just didn't tell the rescue environment to set everything up automatically. At least the Red Hat or Centos rescue does ask this question before running the shell.

the fedora install dvd WILL TELL YOU TO "chroot /mnt/sysimage"
if you use it in RESCUE MODE like you were asked to do

use the install dvd to reinstall grub

but fedora 21 is NOT SUPPORTED any longer

please do a new install using Fedora 23

even for a new install I tried to download Fedora 23 but get an error , failed to download.
I'm using a win7 workstation.
I really don't know how to solve the issue.
I'm kind of stuck.

I can also see that there is more than 3 kernel install on the machine.

If you are unable to get Rescue to work, how about checking the ststus of the system with a LiveCD?

That's no problem in itself.

I would expect to have 4 grub menu entries at least - normal and rescue boot for the old kernel, normal and rescue boot for the new kernel. And mor than that if you updated your kernel at some time. In other words, this is not a problem in itself.

by chance are you using Microsoft Internet Explorer
and trying to save a 1.4 Gig iso to your DESKTOP!!!

and what are you trying to download ?
the 1.4 Gig LIVE image ? ( Fedora-Live-Workstation-x86_64-23-10.iso )

or
one of the spins
https://spins.fedoraproject.org/

and did you go over the install guide
https://docs.fedoraproject.org/en-US...llation_Guide/

that has been NORMAL!!!!! for the past 10+ years
the DEFAULT is to save the last two kernels as a EMERGENCY BACKUP!!!
but might end up getting set to 5 sometimes

Thanks for your help.
I think that the problem is still there because I couldn't give you the right info.
When I launch F21 everything seems to go good till I get that message.
error message

1.5520231 ata1: softreset failed (device not ready)

Do you have an idea how to solve it?
thanks in advance.

berndbausch · 11-30-2015, 05:39 PM

How do you know that this is an error message?
What do you want to solve?
Is there any other message after this one?
