It looks like this firmware update might have been getting stuck on your installation. To try and resolve this issue, please first install the latest updates from the Software Updater or by opening the Terminal (Ctrl+Alt+T) and entering these two commands:
sudo apt update
sudo apt dist-upgrade
After installing these updates, restart your computer before continuing.
Next, it should be possible to manually install this firmware update and clear the pending database afterwards – so this message shouldn't appear again – by opening the Terminal and entering these four commands:
sudo fwupdmgr refresh
sudo fwupdmgr get-updates
sudo fwupdmgr update
Afterwards, restart the computer to apply the changes. Next, open the Terminal again and enter this command:
sudo rm /var/lib/fwupd/pending.db
Finally, restart the computer once more to resolve the issue.
If this still didn't resolve the issue, could you please post the text output after running the four commands (directly above) in the Terminal? If possible, please also include the text output from the following command as well:
fwupdmgr get-devices
In addition, could you please let us know if you've made some prior modification(s) to Zorin OS after installing it to your computer? These modifications may include one or more of the following:
- adding third-party software repositories to your system
- manually editing any system files
- executing unofficial scripts/commands
This information would help us to troubleshoot the issue.
