@carlosgonz What OS was that, and what version of coreboot_util.sh was it? (Approximate date when you downloaded, or value of RELEASES_GIT_HASH in the file, or sha256sum of the file would tell me.)
That should have been fixed by this chunk of code that went into 4.20.1-Purism-1 / PureBoot 27: Update coreboot/SeaBIOS images to 4.20.1-Purism-1/RC1 (150bc8a6) · Commits · firmware / utility · GitLab
