Public bug reported: We are creating AWS AMIs using an EBS surrogate and running this command which completes successfully without any errors (only specific package shown):
Distribution: bionic apt-get install -y --no-install-recommends grub-pc Afterwards when we check the /grub directory it is incomplete: ls -l grub/ total 2348 -rw-r--r-- 1 root root 712 Jan 26 08:18 gfxblacklist.txt -rw-r--r-- 1 root root 2397557 Jan 26 08:18 unicode.pf2 An instance created using the AMI also fails to boot with the following error: No bootable disk The grub-pc version installed is 2.02-2ubuntu8.21. If we install grub manually using grub-install and grub-mkconfig it works with the same version (2.02-2ubuntu8.21). The above mentioned automated AMI creation process running apt-get also works if we downgrade to version 2.02-2ubuntu8.17. Previously we created images with version 2.02-2ubuntu8.18 (as that was the current version at the time) and it worked perfectly, but we noticed that this has been removed from the Ubuntu archive: http://archive.ubuntu.com/ubuntu/pool/main/g/grub2/ (only 2.02-2ubuntu8.17 and 2.02-2ubuntu8.21 still available). >From the changelog it seems likely that the breaking change could have been introduced here: https://launchpad.net/ubuntu/+source/grub2/2.02-2ubuntu8.19 ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New ** Description changed: We are creating AWS AMIs using an EBS surrogate and running this command (only specific package shown): Distribution: bionic apt-get install -y --no-install-recommends grub-pc - Afterwards when we check the /grub folder it is incomplete: + Afterwards when we check the /grub directory it is incomplete: ls -l grub/ total 2348 -rw-r--r-- 1 root root 712 Jan 26 08:18 gfxblacklist.txt -rw-r--r-- 1 root root 2397557 Jan 26 08:18 unicode.pf2 An instance created using the AMI also fails to boot with the following error: No bootable disk The grub-pc version installed is 2.02-2ubuntu8.21.
