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

Question

In Ubuntu MATE 20.04 a Firmware Updater is integrated, it is a GTK front end for fwupd. And I wonder whether there is such thing for the Vanilla Ubuntu GNOME.

Answer 1

1. Firmware Updater
   An new firmware updater UI made with Flutter and based on fwupd is included in Ubuntu 23.10 onwards, it displays firmware updates, and is able to upgrade firmware too — all fetched from the LVFS.
   Canonical has been working on this new firmware-updater app for some years: https://github.com/canonical/firmware-updater
   It can also be downloaded/installed from the Snap Store in previous Ubuntu versions, but with mixed results ...

2. GNOME Firmware (gnome-firmware): Available in the Software Center (as deb package from Ubuntu 20.04 onwards, in the universe repository* and snap):
   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.

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