Hi David,
thanks for your response.
I know these simple rules.

I sent a cleartext e-Mail with my public key to adele at gnupp.de (which is an automated system for practicing encryption and decryption)
and i got an answer which is encrypted. I think it's encrypted with my public key so i should be able
to decrypt it with my private key. That's what i tried. But i got the message while decrypting:

gpg: encrypted with 2048-bit RSA key, ID F742DB29, created 2019-07-23
     "Bernd Lentes (Helmholtz GPG Schluessel) <bernd.lentes at helmholtz-muenchen.de>"
gpg: Fatal: zlib inflate problem: invalid code lengths set

What does this meesage mean ?
