[Bug 1574144] Re: package openstack-dashboard-ubuntu-theme 2:9.0.0-0ubuntu2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Sean McGinnis]

I was able to work around this. May be relative to running on the same
host as keystone.

Running "service apache2 status" showed a port conflict and unable to
bind on port 5000. I stopped keystone and verified the port was no
longer in use, the started apache, reinstalled horizon, then started
keystone again. Multiple checks of apache2 status along the way looked
OK and after all of that was complete I was able to verify
functionality.
