Unable to update "Thunderbolt NVM for Latitude 7275 Device..

I am running Zorin 15 core on my Dell latitude 7275 2 n 1 and it runs very well however, I do have an update which is constantly present and never able to complete. when i try to update all i get this message: Unable to update "Thunderbolt NVM for Latitude 7275 Device Update". I've tried running it from the command line as recommended and this is what I get:

ron@ron-zorin7275:~$ sudo service fwupd restart
ron@ron-zorin7275:~$ sudo fwupdmgr refresh

Any help would be Appreciated even if it's just a way to clear the update from the list. I currently don't own any "Thunderbolt peripherals".

At work at moment - will need to be at home machine to answer this.

Just had a browse and don't know if this thread sheds any light on the issue?:

Thanks for the input I'm learning more ... it would seem that I do have "Boltd" installed but as I don't have any Bolt docks or peripherals to test it with so there's nothing much to see. forcing on power for bolt in the software (boltctl power) did not allow for me to install the update unfortunately.
