Thanks for the tests, there are several interesting things in it.

The first one is that upgrades took very long time and I opened an
upstream issue for that:
https://github.com/mvo5/unattended-upgrades/issues/76

The second is that u-u properly blocks shutdown so this bug seems to
be fixed for the tested case.

The third is the presence of the crash file in 3/ which is a result of
killing u-u --download and it is normal, thus u-u should not generate
it.
I'll fix that separately.
