[pkg-gnupg-maint] Bug#867783: gnupg mystery agent failure

[Ian Jackson]

Package: gnupg
Version: 2.1.18-8

The following occurs during CI testing of dgit:

+ gpg --list-secret
gpg: WARNING: unsafe permissions on homedir '/tmp/autopkgtest-virt-lxc.shared.ar7jp_mz/downtmp/autopkgtest_tmp/gnupg'
gpg: starting migration from earlier GnuPG versions
gpg: porting secret keys from '/tmp/autopkgtest-virt-lxc.shared.ar7jp_mz/downtmp/autopkgtest_tmp/gnupg/secring.gpg' to gpg-agent
gpg: key A3DBCBC039B13D8A/A3DBCBC039B13D8A: error sending to agent: No such file or directory
gpg: error building skey array: No such file or directory
gpg: key 2AC1E075F5ED1B25/2AC1E075F5ED1B25: error sending to agent: No such file or directory
gpg: error building skey array: No such file or directory
gpg: key 14A868BFAC3BD039/14A868BFAC3BD039: error sending to agent: No such file or directory
gpg: error building skey array: No such file or directory
gpg: migration succeeded
+ test 2 = 0

This does not seem to happen in my own tests using adt-run.

Quite why it prints "migration successful" and then exits with status
2 is unclear.

FYI, dgit uses a wrapper for gnupg, like this:

   #!/bin/sh
   set -e
   exec                                                    \
   $DGIT_TEST_REAL_GPG                                     \
	   --agent-program=$DGIT_STUNT_AGENT               \
	   "$@"

And the DGIT_STUNT_AGENT looks like this:

   #!/bin/sh
   set -e
   exec                                                    \
   $DGIT_TEST_REAL_GPG_AGENT                               \
	   --debug-quick-random                            \
	   "$@"
