Bug#830696: apt-key requires gnupg or gnupg2 in apt=1.3~pre2

[Steven Shiau <steven@nchc.org.tw>]

Package: apt
Version: 1.3~pre2
Severity: important

Dear Maintainer,

   * What led up to the situation?
     After upgrading to apt 1.3~pre2, the apt-key does not work. It complains gnupg or gnupg2 not found.
     This is especially when running in a bootstrap environment that gnupg or gnupg2 is not installed.

   * What exactly did you do (or not do) that was effective (or ineffective)?
     steven@debian-TU:~$ apt-key list
     Error: gnupg or gnupg2 do not seem to be installed,
     Error: but apt-key requires gnupg or gnupg2 for this operation.

     steven@debian-TU:~$ dpkg-query -W -f='${binary:Package} ${Version}\n' apt
     apt 1.3~pre2
     steven@debian-TU:~$ dpkg -l gnupg gnupg2

     un  gnupg                    <none>            <none>            (no description available)
     un  gnupg2                   <none>            <none>            (no description available)


     * What outcome did you expect instead?
       Apt should depend on gnupg or gnupg2.
