I am following this tutorial http://truffleframework.com/tutorials/building-dapps-for-quorum-private-enterprise-blockchains for Quorum installation..

I have successfully installed vargrant(Installed Version: 1.8.1).

vagrant ssh

It open up a terminal in virtual machine.

  true

Thus I have successfully completed the Quorum setup.

I am trying to create a new truffle project.

  truffle init bare 

I have config the truffle.js as follows:-

 module.exports = {
      networks: {
         development: {
             host: "localhost",
             port: 22000, // was 8545
             network_id: "*" // Match any network id
        }
    }

};

I have created the SimpleStorage.sol contract and trying to deploy.On deploying it raises the following issue.

   truffle migrate --reset

   Using network 'development'.

   Running migration: 1_initial_migration.js
   Deploying Migrations...
   ... undefined
   Error encountered, bailing. Network state unknown. Review successful  transactions manually.
