I confused TTYNAME and TTYTYPE:

GPG_TTY=xterm

and tried to decrypt a file. The error message i got was also confusing
(end of file):

juergen at lemmy:~ → gpg -d ~/.password-store/Backup/test.gpg 
...
gpg: public key decryption failed: End of file
gpg: decryption failed: No secret key


using this patch:

juergen at lemmy:~ → gpg -d ~/.password-store/Backup/test.gpg 
...
gpg: public key decryption failed: No such file or directory
gpg: decryption failed: No secret key


Regards,

Jürgen
