Package: unattended-upgrades
Version: 0.83.3
Severity: important
Hi,
I _think_ there is an error in unattended-upgrades regarding the proper
handling of changed configuration files.
We have basically two large group of systems where unattended-upgrades
is installed. In one of them we change
/etc/apt/apt.conf.d/50unattended-upgrades, in another (puppet-managed)
cluster we ship /etc/apt/apt.conf.d/99unattended-upgrades-local and
delete /etc/apt/apt.conf.d/50unattended-upgrades
The systems in the first cluster (changed file) have behaved as expected
with the unattended-upgrades update shipped in the last Jessie point

What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.

This leads to unattended-upgrades being held in a half-configured state.
So it seems that unattended-upgrades does detect changed configuration
files, but not deleted ones.
