How to deal with Gnupg error: gpg: no default secret key: No secret key gpg: [stdin]: clearsign failed: No secret key?

问题

I am getting an error:

gpg: no default secret key: No secret key
gpg: [stdin]: clearsign failed: No secret key

My secret keys are available to GPG.

回答1:

It might be difference between gpg1 and gpg2. The secret keys are stored in different ways. You may have both of them.

Try

which gpg gpg2

If you do have both, run:

gpg2 --list-secret
gpg --list-secret

You maybe able to tell that one works, another does not.

Here's the answer: I am using latest gnupg version , but I have to use 0.44 gnupg interface version. I have reinstalled the gnupg.

Then no compilation errors were found. I am able to sign my message. but not able to send the request. The problem is I have not installed LWP::Protocol::Https module which is used by "Useragent" to send the request.( i came to know this that i have not installed the module by keeping simple print statements which shown the problem that LWP::Protocol::Https is not found). So i have installed LWP::Protocol::Https module through cpan. And i am good to go. Finally all is set :-)
