Hi,
I have gpg2 installed with version details as:
gpg (GnuPG) 2.1.21
libgcrypt 1.7.7

When I try to create a pub and sec key I always get this issue:
gpg2 --batch --gen-key /path-to-configfile
gpg: Generating a basic OpenPGP key for our unit test...
gpg: can't create '(null)': No such file or directory

Question 2 :

I have 2 versions
gpg (GnuPG/MacGPG2) 2.0.30
libgcrypt 1.6.6

&
gpg (GnuPG) 2.1.21
libgcrypt 1.7.7

How should I get rid of 2.1.21 version

& what is the diff between gpg and gpp2?

Thanks,
Prateek
