I just got a new Thinkpad Z13 Gen 2, which came with Windows.
I am not able to install Ubuntu 24 without disabling Secure Boot in BIOS or I get the warning "Secure boot violation - invalid signature detected"
Even if I disable Secure Boot to install Ubuntu 24, I cannot enable Secure Boot back or I get the error again.
My previous Thinkpad has Ubuntu 22 and Secure Boot is enabled.
Can anyone help understand what's wrong here? I checked the Secure Boot key management settings on both computers and they look the same. Thank you!
