How to update the Go version

System: Debian/Ubuntu/Fedora. Might work for others as well.

1. Uninstall the exisiting version

As mentioned here, to update a go version you will first need to uninstall the original version.

To uninstall, delete the /usr/local/go directory by:

$ sudo rm -rf /usr/local/go

2. Install the new version

Go to the downloads page and download the binary release suitable for your system.

3. Extract the archive file

To extract the archive file:

$ sudo tar -C /usr/local -xzf /home/nikhita/Downloads/go1.8.1.linux-amd64.tar.gz

4. Make sure that your PATH contains /usr/local/go/bin

$ echo $PATH | grep "/usr/local/go/bin"

Modified for ARM64 versions

#!/usr/bin/env bash

version=$(go version 2>/dev/null || echo "none")
release=$(wget -qO- "https://golang.org/VERSION?m=text" | awk '/^go/{print $0}')

if [[ $version == *"$release"* ]]; then
    echo "The local Go version ${release} is up-to-date."
    exit 0
else
    echo "The local Go version is ${version}. A new release ${release} is available."
fi

release_file="${release}.linux-arm64.tar.gz"

tmp=$(mktemp -d)
cd $tmp || exit 1

echo "Downloading https://go.dev/dl/$release_file ..."
curl -OL https://go.dev/dl/$release_file

sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf $release_file

rm -rf $tmp

cd ~

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

version=$(go version)
if [[ $version == *"$release"* ]]; then
    echo "Now, local Go version is $version"
else
    echo "Failed to update Go. Current version is still $version."
    exit 1
fi

Thanks bro, well scripted and it helped me great work

@wathika-eng Thanks for the ref! 🙏 Indeed, it works like a charm!

Previously, I had Go 1.24 manually installed (extracted, to be precise) in $HOME/apps/go.

The script (wget https://git.io/go-installer.sh && bash go-installer.sh) discovered that
and just ask my confirmation to update it. And that's it! 🥰

i just make shell script for linux
this can update go to latest version

Now you can use go's own toolchain

go get [email protected]

@ggcr Unfortunately, it doesn't work globally (outside of a project/module):

~ ❯ go get [email protected]
go: go.mod file not found in current directory or any parent directory.
	'go get' is no longer supported outside a module.
	To build and install a command, use 'go install' with a version,
	like 'go install example.com/cmd@latest'
	For more information, see https://golang.org/doc/go-get-install-deprecation
	or run 'go help get' or 'go help install'.

This can be a alternative.

wget -qO- https://raw.githubusercontent.com/DieTime/go-up/master/go-up.sh | bash

This will detect your current install, fetch the latest release from go.dev/dl, and replace /usr/local/go with it.
