[pkg-gnupg-maint] Bug#818722: gnupg2: Disabling deprecation warnings to support GnuPG v1/v2 coexistence

[Peter Colberg]

Package: gnupg2
Version: 2.1.11-6
Severity: minor

Dear Maintainer,

My ~/.gnupg/gpg.conf contains the following keyserver options:

  keyserver hkps://hkps.pool.sks-keyservers.net
  keyserver-options ca-cert-file=/usr/share/gnupg2/sks-keyservers.netCA.pem
  keyserver-options no-honor-keyserver-url
  keyserver-options auto-key-retrieve

This causes gpg2 to emit the following deprecation warning:

  gpg: keyserver option 'ca-cert-file' is obsolete; please use 'hkp-cacert' in dirmngr.conf

The ca-cert-file option is required by GnuPG v1 to fetch public keys
over an encrypted connection. Many Debian tools hard-code GnuPG v1,
which makes it challenging to solely use GnuPG v2 [1] on a Debian
system without resorting to a manual dpkg-divert of /usr/bin/gpg.

Would you consider disabling this and similar deprecation warnings in
the Debian gnupg2 package, at least until a system can be configured
to default to GnuPG v2?

Regards,
Peter
