How To Fix the fwupd Service Failure on Ubuntu 20.10

Ubuntu 21

In this article, we will delve into the details of how to fix the fwupd service failure on Ubuntu 20.10. This issue is often associated with the libgusb library, specifically an undefined symbol related to libusb_get_parent. We will guide you through a step-by-step process to resolve this issue.

Quick Answer

To fix the fwupd service failure on Ubuntu 20.10, you can try updating all packages on your system, reinstalling the libgusb library, or referring to the bug report for additional information.

Understanding the Problem

The fwupd service is a daemon that allows session software to update device firmware on your system. If the service fails to start, it can prevent updates and cause system instability. The error message often indicates an issue with the libgusb library, a GLib wrapper around libusb1 that makes it easy to do asynchronous control, bulk, and interrupt transfers with proper cancellation and integration into a mainloop.

Solution 1: Updating All Packages

The first step in troubleshooting this issue is to ensure all packages on your system, including fwupd, are up-to-date. This can be done by running the following command in your terminal:

sudo apt update --fix-missing && sudo apt upgrade

Here, sudo is used to run the command with root privileges. apt update updates the list of available packages and their versions, but it does not install or upgrade any packages. --fix-missing is used to install missing dependencies. && is a bash operator that runs the second command if the first command is successful. apt upgrade is used to install available upgrades of all packages currently installed on the system from the sources configured via sources.list.

If your fwupd service is still failing after updating, proceed to the next solution.

Solution 2: Reinstalling the libgusb Library

Another potential solution is to reinstall the libgusb library. This should be done with caution to avoid damaging the system. To safely reinstall libgusb, use the following commands:

sudo apt-get purge libgusb2
sudo apt-get install libgusb2

The purge command removes the package and its configuration files. After running this command, use install to reinstall the libgusb library.

After reinstalling libgusb, try starting the fwupd service again using the command:

sudo service fwupd start

This command starts the fwupd service. If the service starts successfully, the issue is resolved. If not, proceed to the next solution.

Solution 3: Refer to the Bug Report

There is a bug report related to a similar issue with fwupd. The bug report suggests that the problem should have been fixed in version 1.4.0 of fwupd. However, since Ubuntu 20.10 provides version 1.4.5, it is possible that the bug is not exactly the same. It may be helpful to refer to the bug report for any updates or additional information that could assist in resolving the issue.


In this article, we have discussed three potential solutions to fix the fwupd service failure on Ubuntu 20.10.
