SOLUTION : you must first delete previous golang install prior to installing new go version

type go    # issue this to confirm where your go lives

a typical output :

go is /usr/local/go/bin/go  # delete /usr/local/go not just /usr/local/go/bin/go

so just remove it

sudo rm -rf /usr/local/go  #  OP's missing step else above errors

before you install new version

wget https://storage.googleapis.com/golang/go1.9.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf  go1.9.linux-amd64.tar.gz
