This merely shows the content of a file on your disk.

To sign a key, you need to have it in your keyring. However, based on

I'm thinking you're trying to sign your own key, which is not something
that can be done. There is the so-called self-signature, but it is not
done by --sign-key but rather by changing some aspect of your key with
It would appear (because it asks for a passphrase) that your system has
this private key in its keyring.

You are asking GnuPG to issue a detached signature on a file in your
current directory called REIDgpg. This file appears not to exist.

The man pages are reference manuals, not introductory texts. They are
indeed opaque if you're trying to learn how to do stuff on the command
line.  is better, but it is old. I must admit I'm not really well
acquainted with introductory texts.
You can see which private keys your system has in its keyring by
$ gpg -K
And it would appear you have multiple since GnuPG complains "no default
What are you trying to do? Please try to indicate the end rather than
the means. When you say "I want to sign key A780EFF6" it is not clear to
me what you are trying to accomplish by that. Do you want to make that
key valid? If it's your own key, that won't work. That's for making
other people's keys valid. Your own key should have its trust level set
to "ultimate" to make it valid. This is something that GnuPG does
automatically when creating a key, but not when importing a secret key
that was created with a different GnuPG installation.
Hope that helps a little bit,

I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
