Description Davide Nifosi 2016-05-11 19:05:18 CEST

Description of problem:
Last few kernel packages (last one is 4.6.0-0.rc7.2) do not trigger an update of the GRUB2 menu entries, causing the bootloader menu to show only older kernels.

Version-Release number of selected component (if applicable): 4.6.0-0.rc7.2.mga6


How reproducible: always


Steps to Reproduce:
1. update kernel-desktop to version 4.6.0-0.rc7.2
2. reboot
3. check GRUB2 menu entries: default option still points to the previously installed kernel

Do you have a legacy BIOS system (or UEFI in BIOS mode)?

If so, then you may have noticed the message:

  Cannot find a boot loader installed. Only taking care of initrd

and then this is a duplicate of bug 18407, which was caused by a faulty grub2 some time ago.

In that case, please run, as root

  update-grub2
  grub2-install /dev/sda

(adjust /dev/sda if the bootloader was installed some place else)

Next kernel update should then be fine.

@ Barjac

does "grub2-install" include update-grub2, so that only "grub2-install" is needed?

No. In fact there is no reason to run grub2-install on kernel update, this is only required on grub2 update.

All that is required is update-grub2 and this is now handled by the kernel package/drakboot since the file triggers were removed from grub2.

see bug 18407, after the addition of too many fedora patches, both grub2 and kernel updates had a problem, until i manually invoked grub2-install

I'm on a BIOS system. I haven't seen that particular error message, but after issuing those two commands and updating to kernel 4.6.0-rc7.3 grub.cfg was correctly updated. Thank you
