Public bug reported:
I have just updated my system from Precise to Trusty. During the process
grub attempts to install itself in /dev/sda5 (the root partition). This
fails and complains about blocklists being disabled (embedding not
possible). Annoyingly the process continues and unless you're staring at
the screen (which I was) then you're none the wiser.
The result being an unusable system: grub drops into rescue and at that
point everything is as clear as mud.
The solution was to install grub in the MBR (/dev/sda) from a Trust live
environment. The system is now usable. It took me several hours to work
this out.
There needs to be some sort of protection from this happening in the
future. An ordinary user would have no hope whatsoever in working this
out and an unusable system is the worst-case scenario to any end user
(discounting complete data loss).
Will I be faced with this dreadful problem against on upgrade to 16.04?
Can't the grub upgrade process at least have the sense to try something else
once it has failed?
I had the sense to image the drive before starting the upgrade process,
should it should be reproducible, albeit slowly.
