How to Update Firmware on Ubuntu 18.04
Usually, the default software center in Ubuntu and other Linux handle the update of the firmware of your system. But if you encounter errors with it, you can use fwupd command line tool for updating the firmware of your system.
I use Dell XPS 13 Ubuntu edition as my main operating system. I have done a fresh installation of Ubuntu 18.04 on it and I cannot be happier with the hardware compatibility. Bluetooth, external USB headsets and speakers, multi-monitor, everything works out of the box.
The one thing that troubled me was one of the firmware updates that appeared in the Software Center.
Clicking on the Update button resulted in an error a few seconds later.
The error message was:
Unable to update “Thunderbolt NVM for Xps Notebook 9360”: could not detect device after update: timed out while waiting for device
In this quick tip, I’ll show you how to update the firmware of your system in Ubuntu.
Updating firmware in Ubuntu 18.04
One thing you should know that GNOME Software i.e. the software center in Ubuntu 18.04 is also capable of updating the firmware. But in situations when it fails for some reason, you can use the command line tool fwupd.
fwupd is an open source daemon that handles firmware upgrades in Linux based systems. It is created by GNOME developer Richard Hughes. Developers from Dell also contributed to the development of this open source tool.
Basically, it utilizes the LVFS, Linux Vendor Firmware Service. Hardware vendors upload redistributable firmware to the LVFS site and thanks to fwupd, you can upgrade those firmware from inside the operating system itself. fwupd is supported by major Linux distributions like Ubuntu and Fedora.
Open a terminal and update your system first:
sudo apt update && sudo apt upgrade -y
After that you can use the following commands one by one to start the daemon, refresh the list of available firmware updates and install the firmware updates.
sudo service fwupd start
Once the daemon is running, check if there are any firmware updates available.
sudo fwupdmgr refresh
The output should look like this:
Fetching metadata https://cdn.fwupd.org/downloads/firmware.xml.gz Downloading… [****************************] Fetching signature https://cdn.fwupd.org/downloads/firmware.xml.gz.asc
After this, run the firmware update:
sudo fwupdmgr update
The output of the firmware update could be similar to this:
No upgrades for XPS 13 9360 TPM 2.0, current is 1.3.1.0: 1.3.1.0=same
No upgrades for XPS 13 9360 System Firmware, current is 0.2.8.1: 0.2.8.1=same, 0.2.7.1=older, 0.2.6.2=older, 0.2.5.1=older, 0.2.4.2=older, 0.2.3.1=older, 0.2.2.1=older, 0.2.1.0=older, 0.1.3.7=older, 0.1.3.5=older, 0.1.3.2=older, 0.1.2.3=older
