command 'go' not found

Question

This is not a programming question.

I have a machine running Ubuntu, and I installed Golang on it. It was working fine... I even ran a few programs, but the "go1.11.2.linux-amd64.tar.gz" file was in my home directory so I thought it would be okay to move it to the Downloads directory. After moving it, I can't use any Go command, and I get command 'go' not found. I tried moving the file back to the home directory, but I'm still getting the same error.

Can anybody explain to me what's going on? Thanks!!

Command 'go' not found, but can be installed with:

sudo snap install go         # version 1.11.2, or
sudo apt  install golang-go
sudo apt  install gccgo-go

See 'snap info go' for additional versions.

The commands I used to install Go :

wget https://dl.google.com/go/go1.11.2.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.11.2.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
source ~/.profile

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

Make sure that the GOPATH environment variable is set to /usr/local/bin.

Try adding the exact export command to the ~/.bashrc file.
You need to source the ~/.bashrc file for changes to take place in your current terminal. From next time onward whenever you open a terminal, you should be able to find the go command. This worked for me.

Jos in the comments above is likely 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
