The issue occurs while trying to run SFC Karaf but I think it is not related only to SFC.

>Exception in thread "config-pusher" java.lang.IllegalStateException: Max wait for capabilities reached.Not enough capabilities for 01-md-sal.xml(odl-mdsal-broker).

I guess that the exception is caused by failing installation of feature odl-mdsal-broker. The capabilities are not satisfied because odl-mdsal-broker is not installed at all.

> feature:install odl-mdsal-broker
