Episode 50 of The Linux Podcast dives into FWUPD, the open-source framework that turned Linux firmware updates from a risky manual chore into a reliable, automated process. Lucas and Luna explore how LVFS (Linux Vendor Firmware Service) enables secure UEFI capsule updates across distros, the role of the UEFI firmware update protocol, and why Dell and Lenovo now push BIOS updates through fwupdmgr. They break down the capsule update flow, the ESRT table, and what happens when signed updates meet shim and MokManager. A concrete look at how modern Linux handles low-level hardware updates without breaking your boot chain.
