Is there a GUI for the tool fwupd (firmware updater) in Ubuntu GNOME?

In the Software Center there is a tool (as deb package from Ubuntu 20.04 onwards, in the universe repository* and snap):
GNOME Firmware (gnome-firmware)
GTK front end for fwupd. It can update, reinstall and downgrade firmware on devices supported by fwupd. To install it from the command line (Terminal):
For the deb package (Ubuntu 20.04 and newer): sudo apt install gnome-firmware
For the snap app: sudo snap install gnome-firmware
There is a also flatpak version.

It seems that there is still room for improvement of the app, though. Therefore it could be still better to update the firmware from the command line.

For some devices, firmware updates are directly listed in GNOME Software.

Canonical is working on a new firmware-updater app:
