This is related to bugs around pkexec checking parent, which under some DE can be gone already. See: https://bugzilla.redhat.com/show_bug.cgi?id=879922 https://bugzilla.xfce.org/show_bug.cgi?id=9626#c2
One workaround is to add: StartupNotify=true
which makes Xubuntu work, but can fail other Desktop Environments.
Another workaround is to wrap, ubiquity-wrapper, in a shell script. As e.g. synaptic did.
