[pkg-gnupg-maint] Bug#848596: dirmngr_2.1.16-3 fails to update from 2.1.16-2

[Antonio Niño Díaz]

Package: dirmngr
Version: 2.1.16-2
Severity: important

Dear Maintainer,

I've found this problem when trying to do a full upgrade of my installed
packages.

First, I tried to update everything and this package failed. It wasn upgraded,
so then I tried to only upgrade it to isolate the error messages:


(Reading database ... 220100 files and directories currently installed.)

E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install.  Trying to recover:
dpkg: dependency problems prevent configuration of dirmngr:
 gnupg (2.1.16-3) breaks dirmngr (<< 2.1.16-3) and is installed.
  Version of dirmngr to be configured is 2.1.16-2.
