Updated F29 kernel and grub went bye bye

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Everyone,

I started an update of my F29 system today. Everything seemed to be
going fine until the system locked up. I waited for a few minutes and
then, hesitantly, I power cycled the computer. Sure enough, the boot
didn't start and instead dropped into the grub shell. :/

I managed to manually boot Fedora. I reviewed the dnf history to see
which packages were getting upgraded. I ended up redoing the entire
operation, rewrote the grub2 config for good measure and rebooted: the
same problem occurred again. Drat!

Once the desktop was running again, I decided to only reinstall the
kernel packages that were upgraded. That's when I saw this:

Running transaction

grubby fatal error: unable to find a suitable template
grubby: doing this would leave no kernel entries. Not writing out new config.

I must have missed those errors when I redid the update earlier.

What I've found online so far doesn't reference F29 so I'm not sure
what I can do to fix the problem. 

I did find the following two broken symlinks:

[ranbir@master ~]$ ls -l /etc/grub*
lrwxrwxrwx. 1 root root  22 Oct  4  2018 /etc/grub2.cfg -> ../boot/grub2/grub.cfg
lrwxrwxrwx. 1 root root  31 Oct  4  2018 /etc/grub2-efi.cfg -> ../boot/efi/EFI/fedora/grub.cfg

I don't know if they're supposed to be broken or not.

Does anyone have any suggestions on how I can fix my now broken grub
config?
