fwupdmgr is a command-line tool that allows users to discover, install, and manage firmware updates on Linux-based systems. It interacts with the fwupd daemon, which handles the actual firmware update process. fwupd supports a wide range of devices and firmware types, including system firmware (BIOS/UEFI), device firmware (e.g., SSDs, peripherals), and containerized applications. fwupdmgr provides a user-friendly interface for checking for available updates, listing devices, and initiating firmware installations. The core functionality focuses on providing a consistent and reliable mechanism for keeping device firmware up-to-date, enhancing system security and stability. It's designed to work seamlessly with various Linux distributions and desktop environments.
By default, fwupdmgr uses the Linux Vendor Firmware Service (LVFS), a central repository for firmware updates. However, it can be configured to use other sources.

The firmware update process can be risky, and a failed update could potentially render a device unusable. It is crucial to ensure that the system has a stable power supply during the update process. Backing up important data before initiating a firmware update is strongly recommended. Some updates may require a system reboot to take effect.

fwupdmgr returns 0 on success. Non-zero values indicate failure. Refer to the fwupd documentation for specific error codes and their meanings.

Remotes are sources of firmware metadata. The default remote is the LVFS. fwupdmgr allows enabling and disabling remotes to control the sources of firmware updates. Use 'fwupdmgr enable-remote' and 'fwupdmgr disable-remote' to manage remotes.

fwupdmgr and fwupd were created to address the need for a standardized and secure way to manage firmware updates on Linux. Prior to fwupd, updating firmware on Linux was often a fragmented and vendor-specific process. The project gained significant traction due to its integration with the LVFS, providing a central repository for firmware updates. The development is ongoing, with a focus on expanding device support, improving security, and enhancing the user experience.
