Turns out we cancel the request in snapd-glib, but don't actually send the cancel to snapd - this means that snapd never stops the install.

snapd-glib 1.24 now sends the cancel to snapd, however if you are using a Polkit enabled snapd this method doesn't work through Polkit. This causes an Ubuntu One dialog to pop up if not logged in.

This should be fixed in snapd so that cancels can occur the same way as install/remove.

SRU verification for Zesty:
I have reproduced the problem with gnome-software 3.22.7-0ubuntu3.17.04.7 in zesty-updates and have verified that the version of gnome-software 3.22.7-0ubuntu3.17.04.8 in -proposed fixes the issue. Although when several snaps are installed at the same time and the first snap being installed is cancelled it is the second snap that is cancelled.

Marking as verification-done
