I have an account on the mesa project. I submitted both a GPG and SSH key as part of the account creation process. That happened more than a year ago.
I am running:
echo 'show' | gpg --clearsign
and sending it to firstname.lastname@example.org using the same GPG key I used to create and account, but I am getting the following error:
Error: Unable to check the signature or the signature was invalid:
==> <type 'exceptions.Exception'>: GPG execution failed 10480
Can I please get some help with solving this? I would like to add/modify my email address.
Most likely, the problem is that your MUA wrapped the lines on the message and invalidated the content, or used MIME, or ... any of the other ways to trip up the mail interface.
On the other hand, Mesa no longer uses the mail interface, so this won't be a problem for you any more.
