What is the meaning of "not fully bootstrapped" and how to solve this?

I'm very new to Tezos, so please have some patience with me. I'm curious about experimenting with the smart contracts, but unfortunately I'm failing at an quite early stage already.

In the sandbox as well as in the Carthagenet I'm having the issue that my commands are not being executed (not only with this, also several other commands fail):

$ ./tezos-client activate Warning: Failed to acquire the protocol version from the node Rpc request failed: - meth: GET - uri: http://localhost:8732/chains/main/blocks/head/protocols - error: Unable to connect to the node: "Unix.Unix_error(Unix.ECONNREFUSED, "connect", "")" Error: Unrecognized command. Try using the man command to get more information. 

On Gitlab (issue 568 ) this is debated and claimed the nodes would not be fully bootstrapped. Frankly I don't know what it means or how to solve it?

I'm using the Docker image from the Tutorial assets.tqtezos.com.
