Recently I asked how to update LND to the latest version. He gave me the answer. And I made a small blog post for others. This post is for people who build their LND from sources.
0. upgrade GO
$ sudo rm -rf /usr/local/go
$ sudo tar -C /usr/local -xzf /home/nikhita/Downloads/go1.8.1.linux-amd64.tar.gz
$ echo $PATH | grep "/usr/local/go/bin"
1. stop LND from running $ lncli stop
2. cd $GOPATH/src/github.com/lightningnetwork/lnd $ cd $GOPATH/src/github.com/lightningnetwork/lnd $ git fetch $ git checkout v0.8.0-beta $ make && make install
3. run LND $ lnd --configfile=/home/w4cky/.lnd/lnd.conf
