Package: shim-helpers-amd64-signed Version: 1+15.4+5~deb10u1 I tried upgrading to the latest Debian stable release (10.10) on a 3yr old desktop and received an installation error. The system failed to upgrade shim-helpers-amd64-signed and shim-signed:amd64. The reproducible command and response are below:
