A work around would be to invoke subprocesses using:
_term() {
kill -TERM "$child" 2>/dev/null
}
trap _term SIGTERM
run() {
"$@" &
child="$!"
wait "$child"
}

Bug description:
Title: No pop-up window to warn users that system should not reboot or
shutdown while installing security updates
Summary:
No pop-up window to warn users that system should not reboot or shutdown
while installing security updates
Steps:
1. trigger unattended-upgrades
2. reboot or shutdown system while installing packages
Expected results: There is a pop-up window to warn users that system
should not reboot or shutdown
Actual results: There is no pop-up window to warn users
Additional information:
$ apt-cache policy unattended-upgrades
unattended-upgrades:
Installed: 0.90
Candidate: 0.90ubuntu0.5
$ lsb_release -rd
Description: Ubuntu 16.04 LTS
* APT SRU *
[Impact]
Stopping apt-daily-upgrade.service terminates dpkg and friends by sending the
signals to all processes in the cgroup, and will send KILL quickly after.
[Test case]
Start apt-daily-upgrade.service and stop it while unattended-upgrades is
running.
The upgrade should run to completion or a safe exit point as long as
it takes less than about 900s (which is the timeout for sending kill).
[Regression potential]
Leftover processes might remain in the apt-daily-upgrade cgroup if the
postinst scripts or some apt hooks do something funny.
Shutdown might take longer due to the 900 second timeout.
