Details:
This tripped me up during an update (on ubuntu 17.04 grub2/zesty-updates
2.02~beta3-4ubuntu2.2 amd64).
My lilo.conf on another disk caused the upgrade-grub part of the upgrade to
fail.
After some quick research documented here:
https://answers.launchpad.net/ubuntu/+question/658067
I found the reason, the following part of my lilo.conf:
image = /boot/vmlinuz
append="root=PARTUUID=345215fe-01"
label = Linux
read-only
Contains a space after the last quote in the append line.
Lilo itself does not worry about this and boots properly.
The dequote function in the bash script
"/usr/lib/linux-boot-probes/mounted/50lilo" that parses the lilo.conf file
only removes the second quote on the append line if it is the last character
on the line.
So essentially a non-critical syntax error in lilo.conf,
caused the update of grub to fail (this was during a kernel security
upgrade).
If you need any further details, let me know and I'll do my best to provide
them.
Possible fix would be to trim any extra spaces at the end of the line before
(or during ) the call to dequote.
All the best
M
