Find out where Golang is installed, generally on the fedora it is /usr/local/go Or if you have custom location then check with echo $GOROOT and go to the location and rename go directory using sudo mv go go1.7.3. We keep older version for safety.
Now, go to https://golang.org/dl/ and download suitable version for your system. Lets say downloaded file is in ~/Downloads/ and then execute following (modify paths as required)
sudo tar -C /usr/local -xzf ~/Downloads/go1.8.4.linux-amd64.tar.gz
And you are done here, just check what go version tells you. (should be the updated version)
