Comment # 2 on bug 1040289 from Petr Cervinka

I confirm exactly the same behavior on Tumbleweed, gpg fails with "No secret
key" error.
So far, I tested rollback to previous TW snapshot, gpg works fine with previous
version.

I also did a test with backup(used by gpg2-2.0.24-8.1) of ".gnupg" folder.
Latest gpg proceeds with migration, but fails again.

gpg: starting migration from earlier GnuPG versions
gpg: porting secret keys from '/home/petr/.gnupg/secring.gpg' to gpg-agent
gpg: key E1F7622DF4882DD0: secret key imported
gpg: migration succeeded
gpg: encrypted with 2048-bit RSA key, ID 0BA102312BA1C30C, created 2017-05-03
      "Petr Cervinka <pcervinka@suse.com>"
gpg: public key decryption failed: End of file
gpg: decryption failed: No secret key

It doesn't look related to key corruption in version 2.1.20.
