[Bug 1839051] Re: can't install "grub-install/dev/sda"

[Chris Guiver]

Thank you for your report.

This installation looks like it was caused by a corrupted file system. I
notice in the logs

Aug  6 03:54:25 ubuntu ubiquity: find: ‘/target/boot/efi/EFI/Dell’
Aug  6 03:54:25 ubuntu ubiquity: : Input/output error
Aug  6 03:54:25 ubuntu kernel: [  356.783337] FAT-fs (sda2): error, corrupted directory (invalid entries)

Aug 5 10:01:00 ubuntu grub-installer: grub-install: error: cannot open
`/boot/efi/EFI/ubuntu/shimx64.efi': Read-only file system.

I've marked this bug as incomplete, if you believe I'm in error please
leave a comment as to why, and you can return the status to new.

I suggest you `fsck` your /dev/sda2 (EFI partition) the try again. If it
fails again please change the status of this bug report back to new and
report what you found. If I'm correct the install will succeed after
`fsck`.

If you are unfamiliar with `fsck` (or file system checks) please refer
to https://help.ubuntu.com/community/FilesystemTroubleshooting or for
actual help please refer to https://discourse.ubuntu.com/t/finding-
help/712

I would also suggest using a more modern build of Ubuntu 16.04 LTS
(16.04.6 came out 28-Feb-2019 this year using the then latest kernel
4.15 instead of your used 2017 build which uses a now EOL 4.10 kernel).

Thank you for taking the time to report this bug and helping to make
Ubuntu better
