https://salsa.debian.org/debian/pgpy/-/blob/debian/main/debian/patches/do-not-fail-on-GPGMEError-on-verify.patch

Description: Do not fail on GPGMEError on verify
 GPGME upstream added "--verify" when invoking gpg, which broke the
 undocumented behavior PGPy tests depended on.  This patch ignores
 those failures.
