It comes pre-installed with Windows11 and automatically has secure boot enabled.
You might understand that I can't remove Windows because it's for work.
So I wanted to install LM20.3 as dual boot with Windows11.
A live-disk (USB) doesn't start. The certificate doesn't have a match in the database, is what the BIOS said.
But a Ubuntu 22.04 live disk does start.
The difference I could find is that the certificate used to sign the binaries are from Canonical but have a different year.
LM20.3:
Code: Select all
sbverify --list grubx64.efi
signature 1
image signature issuers:
- /C=GB/ST=Isle of Man/L=Douglas/O=Canonical Ltd./CN=Canonical Ltd. Master Certificate Authority
image signature certificates:

issuer: /C=GB/ST=Isle of Man/L=Douglas/O=Canonical Ltd./CN=Canonical Ltd. Master Certificate Authority
Ubuntu 22.04
Code: Select all
sbverify --list grubx64.efi
signature 1
image signature issuers:
- /C=GB/ST=Isle of Man/L=Douglas/O=Canonical Ltd./CN=Canonical Ltd. Master Certificate Authority
image signature certificates:

I can only add new certificates, but I haven't searched for the Canonical certificate.
