Hi, I am trying to deploy openstack along with monasca monitoring tool using devstack. I was able to successfully run ./stack.sh on ubuntu 18.04 and able to see the dashboard. However when I try to login as admin it says "An error occurred authenticating. Please try again later", even though I am entering the correct password mentioned in the local.conf file.

I have checked if keysotne is running by doing

 sudo systemctl status devstack@keystone.service

and it returns that keystone is active(running).

I see this in var/log/apache2/horizon_error.log:

There should also be a Keystone log with more information. And/or the journal journalctl -u devstack@keystone.

I would also like to see the result of curl, to check if Keystone responds.

thank you for responding! when I do a google search of where keystone logs are located it says /var/log/apache2/ but i don't find any keystone log there. I have ran the two commands you mentioned and added the output in the main question.

There should be a log file under /var/log/apache2. If not, something is very wrong. As confirmed by the result of the curl command, which queries the installed Keystone API versions.

You may find more in the Apache error log or the stack.sh log, but perhaps it's easier to restart from scratch.

CORRECTION: I am looking at an Ussuri Devstack, and there is no keystone log file in /var/log/apache2. However, you should have log messages in the journal. If your journal consists of the three entries above, there is a problem.

I switched to a different machine(Ubuntu 18.04) and installed devstack, still get getting exact same errors(not able to log in to dashboard), i used more minimal local.conf this time. I have updated the main question with the errors that came up while running ./stack.sh and the fixes i used.
