I have created my keys, I have tried through both the CLI and Seahorse.
When I sign an email I get the following error:
Could not create message
Because "gpg: writing to `-'
gpg: DSA key AC806A0E requires a 256 bit or larger hash
gpg: signing failed: General error
", you may need to select different mail options.
