https://puri.sm/posts/february-2018-coreboot-update/ says to install tpm_tools to verify TPM version, yet no such package exists. tpm-tools is the correct package.
Also, https://puri.sm/coreboot/ is incorrect. Instructions for downloading the build script points to a different source (/coreboot but dead link) than ‘Building coreboot from source (official script)’ post on the forum (/youness.alaoui). Also, the output for checking if ME is disabled and neutralized is wrong - it is displaying what the output would show if the ME was only disabled (the v1 Librems).
Finally, on your article on applying Patches for Meltdown and Spectre, no valid OpenPGP data is found, and I think you’ve given an incorrect or old repo. I can’t figure out how to update the microcode on my Librem, could someone help please?
