So, You have added the Zorin PPA and updated Your System like describted in the Link posted from @Storm:

@AZorin

sudo add-apt-repository ppa:zorinos/fwupd

sudo apt update

sudo apt dist-upgrade

And then You rebooted and used the Commands:

@AZorin

sudo fwupdmgr refresh

sudo fwupdmgr get-updates

sudo fwupdmgr update

sudo rm /var/lib/fwupd/pending.db

and then rebooted again, yes?
