Ubuntu – Ubuntu bootable drive- Couldn’t get size: 0x800000000000000e ; MODSIGN: Couldn’t get UEFI db list


I made a bootable drive with Etcher on my Mac. I followed the instructions to erase and properly partition the USB flash drive. It is MS-DOS FAT 32 with a GUID partition scheme.

When I try to boot or check for errors I get a black screen as shown below with the errors listed in the title:

[   8.608429] Couldn't get size: 0x800000000000000e
[   8.608453] MODSIGN: Couldn't get UEFI db list
[   8.626775] Couldn't get size: 0x800000000000000e

In that order. I have tried on two different USB drives so far. I made sure to eject the disk when prompted to initialize or eject after Etcher finished installing and validating the ISO. The ISO was downloaded from Ubuntu's page. It is 18.04.1-desktop-amd64.iso
I am using a late 2011 Macbook Pro Laptop. Is the ISO possibly the wrong format for my device?

Also when I select the option to boot on restart I get two EFI boot options, both of which do the same thing.

I had the same issue with:

AMD Athlon 200GE Dual-core MSI B450I Gaming Plus AC

I followed this guide to install Elementary OS, should be the same with Ubuntu


Once installed I used the same nomodeset to boot into Elementary OS

Once booted in I updated the kernel to 4.19 using this guide


I had no more issues after that
