Hi Trying to install single install on Ubuntu, repeatedly failing at post processing stage for keystone with

status: error message:hook failed: "config-changed

I didn't see any error in the commands.log.

Once the keystone error appears most of the work load status turns to waiting and message is "incomplete/missing relations: identity"

At this stage my login to dashboard fails!! Appreciate some help to cross this hurdle.
