Dear Maintainer,

I just checked if Softwares application offered any updates for system.

sudo fwupdmgr refresh did not solve this issue.

Inside Softwares application when I press on "Update" button on "Device
Firmware - Latitude 7X00", then popup message appears "Unable to update
Latitude 7X00 System Update as download failed: failed to download
https://fwupd.org/downloads/... Unknown Error: Access Denied -- you must set
