Error 'grub-efi-amd64-signed' and 'shim-signed' - Dual boot Ubuntu 18.04.01/Windows10

[cmasso6]

Dear community,

I keep getting the same error message each time I run an "apt-get" command:

I installed Ubuntu 18.04 along side Windows 10 on a Surface Pro 4
I had some issues with the installation process with a "grub-efi-amd64-signed"
I resolved the issue following this workaround: https://bugs.launchpad.net/ubuntu/+s...r/+bug/1771651
Now I can boot Ubuntu and it works fine apart from this error.

I run boot-repair which did not resolve the problem
Here is the boot-info report: http://paste.ubuntu.com/p/yym3Xmrz2N/

The system:

Linux sp4 4.15.0-38-generic #41-Ubuntu SMP Wed Oct 10 10:59:38 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Thank you in advance for your help,
Best

Can you please show us the output from:

dpkg -l grub\*

These type of problems can be a real pain.
While we are here could you also include this as well:

cat /etc/fstab

Thank you for your answer

yuck....This one is a mess,
This is where i get thrown "# /boot/efi was on /dev/nvme0n1p1 during installation
#UUID=36A3-AA7B /boot/efi vfat umask=0077 "
And due to the fact that I myself never dual boot with Windows. (I just don't use it). but this might help hone in on it bit more:

sudo update-grub

post back the return please.

Here it is

Well lets see if we can get lucky.

sudo apt update
sudo apt upgrade

[cmasso6]

Nope, no luck :/
I get the exact same message

[1fallen]

Please have a good back-up in place before proceeding.
Kind of a stab in the dark, but try

sudo apt remove --purge grub\*
sudo apt install grub-efi
sudo apt autoremove
sudo update-grub

[23dornot23d]

Could not prepare Boot variable: No space left on device
grub-install: error: efibootmgr failed to register the boot entry: Input/output error.

Might be worth also looking at space on the boot drive .........
but if the last commands have been done - it may also give some room for it to now work .....

mmm ..... also ..... https://bugs.launchpad.net/ubuntu/+s...tatus:list=NEW

I had that error on one of my systems, it took a while and/or UEFI replacement, grub update and various housecleaning.

https://askubuntu.com/questions/1072...stall-error-ef

In my case I found grub or UEFI finding all my entries in the ESP as I had backed up my /EFI/ubuntu folder several times. Still lots of room in my ESP.
But I could tell grub or UEFI was adding UEFI boot entries as they had the name of my backup folders.
Post this:
sudo efibootmgr -v

I totally updated my UEFI, but newest version was version I had, so I just reinstalled it. It will reset many settings to defaults. So keep track of what you changed like UEFI Secure boot, allow USB boot, and any others.
I housecleaned my ESP so it only had /EFI/ubuntu. If you have Windows or other systems you will want to keep those also.

If the efibootmgr -v shows lots of entries, we should houseclean out all duplicates or old entries. Do that before updating UEFI.
Delete entry change XXXX to correct entries. Some UEFI require all 4 HEX char, other just need 1 or 2 significant char.
sudo efibootmgr -b XXXX -B
Delete Ubuntu
