Updating the firmware doesn’t work with Ubuntu’s software center

On the Dell XPS 13 9360 updating from firmware version 1.3.2 to 1.3.5 by clicking on the CAB file [1], I am asked if I want to open it with the software center, I say yes, and the applications opens. I am asked, if I want to update. I click yes, but nothing happens then.

Using the command line tool works though with `fwupdmgr install path/to/update.cab`, after connect the device to power.
