Install Go

Check the latest stable version of the arm64 binary at https://golang.org/dl/ and download it.
```
$ cd /tmp
$ wget https://go.dev/dl/go1.19.3.linux-arm64.tar.gz
```
Check on the download page what is the SHA256 checksum of the file, e.g. for the above: 99de2fe112a52ab748fb175edea64b313a0c8d51d6157dba683a6be163fd5eab. Calculate the SHA256 hash of the downloaded file. It should give an “OK” as an output.
```
$ echo "99de2fe112a52ab748fb175edea64b313a0c8d51d6157dba683a6be163fd5eab go1.19.3.linux-arm64.tar.gz" | sha256sum --check
> go1.19.3.linux-arm64.tar.gz: OK
```

Install Go in the /usr/local directory.

$ sudo tar -xvf go1.19.3.linux-arm64.tar.gz -C /usr/local
$ rm go1.19.3.linux-arm64.tar.gz

Add the binary to PATH to not have to type the full path each time you use it. For a global installation of Go (that users other than “admin” can use), open /etc/profile.
```
$ sudo nano /etc/profile
```
Add the following line at the end of the file, save and exit.
```
export PATH=$PATH:/usr/local/go/bin
```
To make the changes effective immediately (and not wait for the next login), execute them from the profile using the following command.
```
$ source /etc/profile
```
Test that Go has been properly installed by checking its version.
```
$ go version
> go version go1.19.3 linux/arm64
```

Check the currently installed version of GO.

$ go version
> go version go1.19.3 linux/arm64

Check for the most recent version of Go on their site Downloads section.
Remove the current installation.
```
sudo rm -rvf /usr/local/go/
```
Download, verify and install the latest Go binaries as described in the Install Go section of this guide.
