パッケージファイルからbitcoinをインストールします
vagrant@vagrant-ubuntu-trusty-64:~/bitcoin$ sudo apt-add-repository ppa:bitcoin/bitcoin
vagrant@vagrant-ubuntu-trusty-64:~/bitcoin$ sudo apt-get update
vagrant@vagrant-ubuntu-trusty-64:~/bitcoin$ sudo apt-get install bitcoind bitcoin-qt

Bitcoin server starting

vagrant@vagrant-ubuntu-trusty-64:~/bitcoin$ bitcoin-cli getinfo
error code: -32601
error message:
getinfo

This call was removed in version 0.16.0. Use the appropriate fields from:
– getblockchaininfo: blocks, difficulty, chain
– getnetworkinfo: version, protocolversion, timeoffset, connections, proxy, relayfee, warnings
– getwalletinfo: balance, keypoololdest, keypoolsize, paytxfee, unlocked_until, walletversion

bitcoin-cli has the option -getinfo to collect and format these in the old format.
