Being very new to Ubuntu, which I really like, I now get the following message when I try and send an email:

"gpg: skipped "": secret key not available
gpg: signing failed: secret key not available
", you may need to select different mail options

Can anyone help me? I've checked my account set up, and nothing changed. I did install this evening Firewall Configuration and GIMP. Appreciate it. I'm still using version 11.04 by the way.

Hello and welcome to Ubuntu and Ask Ubuntu! Did you put in the xxxxxxx to protect private information or is that really your server? What is your email provider? – William Nov 28 '11 at 3:11

I believe you may have accidentally configured Evolution to use GPG keys. Have a look at this article - can you confirm that you have the PGP/GPG Key ID field empty in the following window:

enter image description here

I suspect you may accidentally entered there

I had same problem

You have two keys, one is pub and other is sub

edward@computer:~$ gpg --edit-key CEF41E5C
gpg (GnuPG) 1.4.18; Copyright (C) 2014 Free Software Foundation, Inc.

Secret key is available.

pub  4096R/CEF41E5C  created: 2015-07-27  expires: never       usage: SC  
                     trust: full          validity: unknown
sub  4096R/BB84D566  created: 2015-07-27  expired: 2015-08-26  usage: E   
[ unknown] (1). edward torvalds (encrypt the world) <>

as you can see my pub key is fine but sub key is expired
now select sub key

key 1



then enter the time after which it should expire, I choose 0 which means never


Done! :-)
