unix - gpg decryption fails with no secret key error

Question

I have a gpg .key file that is used as passphrase for decrypting a .dat.pgp file. The encrypted .data.pgp file gets successfully decrypted on one server with same .key file using following command

cat xxx_gpg.key | /usr/bin/gpg --batch --quiet -o xxx.dat --passphrase-fd O -d xxx.dat.pgp

But, when I move same key to another server xxx_gpg.key and run same above command, I get following error -

gpg: decryption failed: No secret key

EDIT:

I find that gpg --list-secret-keys returns some data on server where it works but no results are returned for other server.

How can we configure secret key

Answer 1

I just ran into this issue, on the gpg CLI in Arch Linux. I needed to kill the existing "gpg-agent" process, then everything was back to normal ( a new gpg-agent should auto-launch when you invoke the gpg command, again; ...).

• edit: if the process fails to reload (e.g. within a minute), execute gpg-agent in a terminal and/or reboot ...
