### Download and extract repository

#### AMD and Intel compatible processors

```bash
GOVER=$(curl https://go.dev/VERSION?m=text | head -n 1)
wget https://golang.org/dl/${GOVER}.linux-amd64.tar.gz && \
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf ${GOVER}.linux-amd64.tar.gz
```

#### **ARM processors**

```bash
GOVER=$(curl https://go.dev/VERSION?m=text | head -n 1)
wget https://golang.org/dl/${GOVER}.linux-arm64.tar.gz
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf ${GOVER}.linux-arm64.tar.gz
```

**NOTE**: That will install latest version of Go

**Install previous version**

```json
GOVER=go1.20.3
wget https://golang.org/dl/${GOVER}.linux-amd64.tar.gz
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf ${GOVER}.linux-amd64.tar.gz
```

### Add Go environmental variables

Set of variables, which should be set for user(s) with need to build Go apps.

That can be placed in `${HOME}/.profile` or `${HOME}/.bashrc` or any other shell-specific file, whic sets variable during logon

```bash
# add environmental variables for Go
if [ -f "/usr/local/go/bin/go" ] ; then
    export GOROOT=/usr/local/go
    export GOPATH=${HOME}/go
    export GOBIN=${GOPATH}/bin
    export PATH=${PATH}:${GOROOT}/bin:${GOBIN}
fi
```

**NOTE:** To make sure that Go-specific environment will be added to new users profiles below code needs to be added to `/etc/skel/.profile`.

### Important

Once all changes are applied and files installed make sure all shell instances will be closed and then logoff and logon again to system.

That way all environmental variables will be set correctly.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.chaintools.tech/home/readme/install-golang.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
