Debian 13.6 security update patches over a hundred advisories in trixie

Most PCs still run with a UEFI Secure Boot certificate authority, installed by default since 2013, that has now expired. That certificate signed the bootloaders letting machines start with Secure Boot turned on. Its expiry sits at the center of the sixth update to Debian 13, codenamed “trixie.” The point release carries mostly security corrections along with a few fixes for serious problems.
