Install of grub-efi-amd64-signed 1.66.17+2.02~beta2-36ubuntu3.17 from xenial/proposed-updates fails to install with a message about /usr/lib/grub/i386-xxxxx/modinfo.sh not found, and I had a strange hard reboot during install...

I had to reinstall version 1.66.16+2.02~beta2-36ubuntu3.16 to boot my machine.

$ lsb_release -rd
Description: Ubuntu 16.04.3 LTS

Hello,

I made another test with grub-efi-amd64-signed 1.66.17+2.02~beta2-36ubuntu3.17, and an reboot occured during installation.

I had to reinstall version 1.66.16+2.02~beta2-36ubuntu3.16 again to boot my machine (booting with an USB key, downlading all the 6 packages involved and chrooting to install them).

My motherboard is an Intel DP55WB and my CPU is :

$ cat /proc/cpuinfo | egrep "model name|vendor_id" | sort | uniq
model name : Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz
vendor_id : GenuineIntel

That would not be caused by the grub maintainer scripts unless your firmware
has a fault.

Hello,

I blocked the install of 3.17 version with the help of Synaptic.

I saw that an 3.18 version was released, and gave it a try.

The PC didn't reboot during install, but didn't reboot : EFI was cleared and I had to reinstall 3.16 version booting with an USB key and chrooting (I'm glad I kept the .deb in /var/tmp ;-)

I migrated yesterday to 18.04 beta and the 1.93+2.02-2ubuntu8 version works like a charm.

As it seems I'm the only affected by this bug, you can close it.

Thanks!
