Permission Denied: curl -sSL http://bit.ly/2ysbOFE | bash -s -- 2.2.2 1.4.9

I am trying to complete the Lab Setup for the Hyperledger Fabric training and facing issues. I am running Ubuntu and have followed the Setup instructions to the "T". I am also totally new to Linux so these errors are confusing for me and I am not sure how to resolve them. I have pasted the output of the command that I ran. Primarily, I am getting several Permission Denied Errors and that could be the cause of the error I am getting when running the very last command which is:

faruk@HLFT-VirtualBox:~/go/src/github.com/hyperledger/fabric-samples/test-network$ sudo ./network.sh up createChannel -ca -s couchdb

I get the following error:

ERROR: The Compose file './docker/docker-compose-ca.yaml' is invalid because:
networks.test value Additional properties are not allowed ('name' was unexpected).

I am unable to proceed any further. Any help would be greatly appreciated. Thank you in advance.
