  • How long you been waiting for peers? Usually it takes few hours. At least this is what happened with my light node.

  • Are you behind a firewall or NAT network? Try port forwarding the p2p port to the machine running geth.

When full nodes decide to serve light nodes, they use much more bandwidth and read a lot off of their disk, so most people don't serve light nodes. I've had problems running any kind of nodes on Ubuntu, so that might be your problem. Also, there are tons of light nodes waiting for new ones. Don't try to run a light node during ICO, you will never find one.

  • if I add some node as peers by admin I found the node by etherscan nodes. Is this correct?

  • Are you saying you found etherscan's nodes? If you add any light node serving node, and add it via admin.addPeer, it will start serving you. etherscan nodes are just like any nodes
