Guide to Updating Linux Firmware on Ubuntu

Firmware in Linux systems plays a crucial role in ensuring that hardware devices operate efficiently and securely. This guide provides comprehensive details on how to update firmware on Ubuntu, using tools and best practices tailored for both open-source and proprietary firmware solutions.

Understanding Linux Firmware

Linux firmware is the low-level software that controls and manages the hardware components of a system. Depending on the hardware manufacturer, firmware can be either open-source or proprietary. Open-source firmware, like Libreboot and Coreboot, aligns with the Linux ethos of transparency, allowing users to view, modify, and enhance the software. Proprietary firmware, provided by manufacturers, is essential for the functionality of various devices but often lacks the openness of its counterparts.

Tools for Managing Linux Firmware

The primary tool for managing firmware on Ubuntu is fwupd, which supports firmware updates from a multitude of vendors. It integrates seamlessly with GNOME Software, providing a user-friendly interface for managing firmware updates. Installation and usage of fwupd are straightforward:

sudo apt update
sudo apt install fwupd
fwupdmgr refresh
fwupdmgr update

Open-Source Firmware

Users who prefer open-source solutions can consider Libreboot and Coreboot, which are alternatives to proprietary BIOS. These open-source projects offer greater control over your device but may require more technical expertise to install and manage.

Updating Proprietary Firmware

Proprietary firmware updates are also managed through fwupd. However, it's crucial to ensure that your system's proprietary drivers are compatible with the latest firmware updates. Here's how to check and install proprietary drivers in Ubuntu:

sudo ubuntu-drivers autoinstall

Best Practices for Firmware Updates

Keeping firmware up to date is crucial for security and performance. It's recommended to schedule regular checks for firmware updates. Here's a cron job example to automate the check using fwupdmgr:

0 3 * * * /usr/bin/fwupdmgr refresh && /usr/bin/fwupdmgr update

Challenges and Considerations

While updating firmware, users may encounter issues such as compatibility problems or the risk of bricking devices. It is crucial to perform updates during periods of minimal use and to ensure power stability to prevent any disruptions during the update process.


Updating your Linux firmware is an essential part of maintaining the health and security of your hardware. Whether using open-source or proprietary firmware, tools like fwupd make the process more accessible and safer.
