Description Florian Hubold 2019-07-08 12:56:40 CEST

Description of problem:

Saw this once during the upgrade to mga7 already, probably when one of the post-hooks tried to run bootloader-config, but I didn't gave much on it as the upgrade was still only half-complete. Now that the upgrade is complete, this still happens and prevents bootloader-config from completing its job.

I'm not sure where /usr/lib/libDrakX/devices.pm picks up sdd as no such device exists and I also don't find that anywhere under /etc. It could be about the sr0 or pktcdvd0 but this shouldn't prevent bootloader-config from completing.

FWIW, in comparison both dracut and update-grub2 work without issues.

After checking a bit more, stumbled about the cause for this, it's /boot/grub2/install.sh which contains "grub2-install /dev/sdd" instead of "grub2-install". Although that has been there since Dec. 2017, and has not been an issue until now.

After removal of /dev/sdd from /boot/grub2/install.sh bootloader-config only returns: "Cannot find a boot loader installed" :/

Re-ran drakboot to reinstall grub2, now everythings working fine.
/boot/grub2/install.sh now contains the device selected in drakboot "grub2-install /dev/sdc". So it seems I changed bootloader location some time in the past and can't really remember, closing this one.
