I'm working on the hyperledger blockchain on Ubuntu 18-04 LTS via this tuto hyperledger.github.io/composer/latest/tutorials/developer-tutorial . I have installed all the pre-requisites and in this step of running "composer network install", I faced this issue and tried some solutions but still not working. Any help please ? Thanks !
~/tutorial-network$ composer network install --card PeerAdmin@hlfv1 --archiveFile tutorial-network@0.0.1.bna
✖ Installing business network. This may take a minute... Error: Error trying install business network. Error: No valid responses from any peers. Response from attempted peer comms was an error: Error: Failed to connect before the deadline Command failed
Just mentioning this for others who might face this issue - While in your case fabric network was not running, in my case it was an issue with proxy. Once I cleared that, I was able to deploy successfully.
