Decryption fails with "No secret key"

[Gabriele Pohl]

Hi

After upgrading my PC to Fedora 30 

gnupg2-2.2.17-1.fc30.x86_64
gnupg2-smime-2.2.17-1.fc30.x86_64
gpgme-1.12.0-1.fc30.x86_64
gnutls-3.6.10-1.fc30.x86_64
libgcrypt-1.8.5-1.fc30.x86_64
libgpg-error-1.33-2.fc30.x86_64

a problem with decrypting came up.

Encryption works:

$ gpg --verbose --output test.txt.gpg --recipient contact at dipohl.de --encrypt test.txt
gpg: Note: signature key E747789CEA208551 expired Fri 06 Jun 2014 07:46:32 PM CEST
gpg: using pgp trust model
gpg: using subkey 4BB3049F19616A80 instead of primary key 9C7646202CE0CBB2
gpg: automatically retrieved 'contact at dipohl.de' via Local
gpg: This key belongs to us
gpg: reading from 'test.txt'
gpg: writing to 'test.txt.gpg'
gpg: RSA/AES256 encrypted for: "4BB3049F19616A80 Gabriele Pohl <contact at dipohl.de>"

$ ls -l test.txt*
-rw-rw-r--. 1 gap gap 119 Jan  3 13:04 test.txt
-rw-rw-r--. 1 gap gap 697 Jan  3 13:07 test.txt.gpg

But decrypting fails:

$ gpg --verbose --decrypt test.txt.gpg 
gpg: public key is 4BB3049F19616A80
gpg: using subkey 4BB3049F19616A80 instead of primary key 9C7646202CE0CBB2
gpg: encrypted with 4096-bit RSA key, ID 4BB3049F19616A80, created 2016-09-05
      "Gabriele Pohl <contact at dipohl.de>"
gpg: decryption failed: No secret key

The secret key is available:

I hope you can help me to solve the problem.


Thanks and kind regards,
