zypper doesn't work with official opensuse repositories

[Markus Ueberall]

1) The release of Ubuntu in use:
$ lsb_release -rd
Description: Ubuntu 16.04.1 LTS
Release: 16.04

2) The version of the package (see https://bugs.launchpad.net/ubuntu/+source/zypper/+bug/1638306):
$ LANG=C apt-cache policy zypper
zypper:
  Installed: 1.12.4-1build1
  Candidate: 1.12.4-1build1
  Version table:
 *** 1.12.4-1build1 100
        100 /var/lib/dpkg/status
     1.12.4-1 500
        500 http://archive.ubuntu.com/ubuntu xenial/universe amd64 Packages

3) What was expected to happen: zypper should work with the official opensuse repositories

4) What happened instead: zypper failed to build the cache
(NB the commands below are part of the /usr/share/lxc/templates/lxc-opensuse script, tested w/ v13.2, but v42.x yield the same errors)

I ran into the same issue. the issue is that the "zypper" package is using /usr/bin/gpg2 to validate repository signatures, but zypper does not depend on that. the fix is to merely install "gnupg2" beforehand.

Maybe this could be fixed by adding a runtime dependency on gnupg to the package.

Status changed to 'Confirmed' because the bug affects multiple users.

gnupg2 I meant, sorry.
