fwupdmgr

fwupdmgr is a command-line tool used for managing firmware updates on Linux systems. It is specifically designed to update firmware on devices that support the Linux Vendor Firmware Service (LVFS). With fwupdmgr, users can check for available firmware updates, download and install them, and even roll back to a previous version if needed.

fwupdmgr works by connecting to the LVFS server and querying for compatible updates for the connected devices. It provides detailed information about the available updates, such as version numbers, release dates, and descriptions. The tool is capable of automatically applying updates for devices that support unattended upgrades, ensuring a seamless process.

Furthermore, fwupdmgr offers additional features like reporting the current firmware version, listing devices that have outdated firmware, and even checking the integrity of firmware images before installation. It supports both local and remote firmware updates, allowing users to update devices connected directly to their system or through a network connection.

To use fwupdmgr, users need to have administrative privileges, as it requires root access to perform firmware installations. The tool is typically available on popular Linux distributions and can be executed directly from the command line. It provides a convenient and straightforward way to keep firmware up to date, ensuring security improvements and bug fixes for supported devices.
