Re: Shim error message about "blocked executable in ESP"

Tumbleweed does not use boot-repair by default. The error you're encountering is due to the `shim.efi` file being blacklisted in the UEFI Secure Boot Forbidden Signature Database (DBX). To resolve this, ensure that both GRUB and Shim are updated to the latest versions available. https://retrobowl.college
