I believe it actually says "connmand not available", meaning that connmand (Connection Manager daemon) is not running for some reason. I'm guessing that connmand doesn't start because NetworkManager is already running.
To debug this, first check that connman is installed:
dpkg -l connman
Syslog might contain hints why connman is not starting:
grep connmand /var/log/syslog
And then check that connmand is running and NetworkManager is not:
ps aux | less
Also you might want to revisit the installation instructions here:
