+Subject: Support tofu+pgp trust model in GnuPG
+Bug-Debian: https://bugs.debian.org/955271
+Forwarded: no
+
+GnuPG supports a trust-on-first-use layer that sits on top of the
+standard PGP trust model. If this is enabled, 'gpg --list-keys' needs
+write and lock permissions on the TOFU database to return any useful
+data. Allow this access through AppArmor.
