[aur-general] SSH Key Denied Problem

Fri Jul 9 01:09:35 UTC 2021

Well, as soon as I sent this I think I figured it out.  There is an error
message when updating the SSH key, but I don't see it because it's off
screen.  When I first select "update" after changing the key, the key looks
like it has been changed.  But if I come back to the page later, it's the
old key again.  I finally noticed the error message and it was asking for
me to enter my password.  After I did that it appears everything is working
just fine.

Thanks for taking a look into this!
