Yuan-Chen, I installed fwupd from your ppa. Logitech fw-update works, thanks.
unfortunately system firmware on my xps13 does not as fwupd complains about missing signed bootloader:
"UpdateError: missing signed bootloader for secure boot: /usr/lib/fwupd/efi/fwupdx64.efi.signed cannot be found"
I hope, once working correctly this ends up either in ubuntu bionic or at least in 'dell-support' (as 1.2.5-1~somerville1 there can't handle logitech :()
