Installing Go

To install Go, do the following:

1. Remove any existing Go installations

    sudo rm -rf /usr/local/go

   Note: Be sure to backup any existing Go installations before removing them.

2. Find the latest version of Go from https://golang.org/dl/ then download it

    wget https://dl.google.com/go/go1.17.7.linux-amd64.tar.gz

   Note: Change go1.17.7.linux-amd64.tar.gz to the most recent version of Go.

3. Extract the archive

    tar -xvf go1.17.7.linux-amd64.tar.gz

4. Set permissions on the extracted files

    sudo chown -R root:root ./go

5. Move the directory to the /usr/local/go

    sudo mv go /usr/local

6. Set the PATH variable

    echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.profile

7. Set the GOPATH and GOBIN variables

    echo 'export GOPATH=/usr/local/go' >> ~/.profile

    echo 'export GOBIN=/usr/local/go/bin' >> ~/.profile

8. Log out and log back in to apply the changes

9. Verify the installation

    go version

   You should see something like:

   go version go1.17.7 linux/amd64

10. Verify the GOPATH and GOBIN variables are set correctly

     go env

    You should see the GOPATH and GOBIN variables set correctly.

Purging old Go version

If you have issues getting the latest version of Go working, it might be because you have an older version of Go installed with apt-get. To remove the old version of Go, do the following:

sudo apt-get purge golang*

Note: After doing this, you might need to reinstall Go. But first log out and log back in and test with go version.
