[Bug 1767767] Re: package shim-signed 1.34.9+13-0ubuntu2 failed to install/upgrade: installed shim-signed package post-installation script subprocess returned error exit status 1

[Steve Langasek]

The log suggests that you had successfully installed the shim-signed
package previously, but when attempting to upgrade the package, it
failed because the system was not detected to be a UEFI system.

Did you install in UEFI mode, and subsequently switch the system to BIOS
mode instead?
