Comment 2 for bug 1571679

Yes, I have hit this bug with my laptop during xenial release sprint. My understanding was that we have agreed to make -signed to be installed by default, however naive approach was shut-down due to dependency cycle (can't remember exactly now). At the time I have manually installed -signed to get the fwupdates working. But we should be install -signed by default. Similar to how installers no longer make destinction between signed/unsigned installs -> we always install both, as one can flip between signed and unsigned boot throughout the lifetime of the machine.
