[Pkg-gnupg-maint] Bug#772897: gnupg2: upgrade to 2.1 fails to import secret keys

[Ximin Luo]

Package: gnupg2
Version: 2.1.0-1
Severity: important

When upgrading to 2.1, if an existing 2.0 gpg-agent is running, then the migration of secret keys fails silently with an unobvious warning the first time you run gpg2 after the upgrade.

This can be circumvented, by killing all running gpg-agents during the upgrade. GPG 2.1 will automatically start them up when missing, so this should be safe.

An alternative is to pop up a warning during the install process, similar to how libc upgrades pop up a warning that prompt you to restart various services.
