command 'go' not found

Jos in the comments above is like correct. You need to add the change to PATH in your .profile. From the install doc (emphasis added):

Add /usr/local/go/bin to the PATH environment variable. You can do this by adding this line to your /etc/profile (for a system-wide installation) or $HOME/.profile:

export PATH=$PATH:/usr/local/go/bin

From: Installed golang still go: command not found #20

Use this command:

sudo apt update && sudo apt install golang

Use nano ~/.profile to edit the file and add the following:

export PATH=$PATH:/usr/local/go/bin

Save the file using the command source ~/.profile. Check the version:go version
