Comment 30 for bug 1766890

I spent a bit of time looking into this one, and I really have no idea. I followed Brian's lead and restored the apt-clone file in comment #20, which makes the bug reproduce.

I upgrade all the machine to all of xenial-{proposed,security,updates} and it still reproduces. I updated desktop-file-utils and glib2.0 to have *all* of their triggers be noawait, even the one which actually needs to be await (schemas).

ubuntu@laney:/var/lib/dpkg/info$ more gnome-menus.triggers bamfdaemon.triggers libglib2.0-0\:amd64.triggers mime-support.triggers desktop-file-utils.triggers

My final attempt was to make *all* file triggers noawait, by editing /var/lib/dpkg/info/*.triggers and /var/lib/dpkg/triggers/File. This also failed, but maybe this isn't a good way to do cowboy that change.

What is this?
