Anyone who does have the hardware and skills to be able to reproduce and
attach a debugger you need to install the debug symbols for it to be
useful. By default Ubuntu buildd's strip debug symbols and places them in
ddebs. The automatic crash retrace bot will use these symbols to generate
useful backtraces but for attaching a local debugger you will need them
locally installed.

You can find the debug symbols that match your architecture and version
here. Install all 3 packages that match your architecture and version
(libdfu1, libfwupd1, fwupd).
