Hey all Its been a week that I am stuck at HTTP 500 error while installing keystone kilo. I tried everything including mysql and apache2 ports and even keystone.conf but believe me everything was correct. I don't know why I am getting this error. Please help me. Below is the traceback of 'sudo --debug service create --type identity keystone' command. Please tell me what is this traceback indicating?
