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"

Oh my. 😭

Oh my zsh

Thanks man! @udhos

Thank you

Faced a strange issue with Goland when update was done. Goland wasnt able detect Go SDK.
Solution for is here - https://stackoverflow.com/questions/19108421/the-selected-directory-is-not-a-valid-home-for-go-sdk

Need to edit src/runtime/internal/sys/zversion.go file, for anyone facing similar issues.

good

Thank you ! Very clear !

Nicely done!

@udhos legend

Thanks :) A lovely simple process :)

Download : curl -LO https://go.dev/dl/go1.18.2.linux-arm64.tar.gz
things like that

If you are facing -bash: /usr/local/go/bin/go: cannot execute binary file: Exec format error error, please make sure that you are installing with correct OS version of go binary file.

• remove rm-rf /usr/local/go/bin/go for older version
• then tar -C /usr/local -xzf go again

thanks for the help ...

Great work man!

Thanks @udhos !

I paired it with installation of mosint

Thank's Man

Thanks!

$ cat upgrade_go.sh

#!/usr/bin/env bash

version=$(go version|cut -d' ' -f 3)
release=$(curl --silent https://go.dev/doc/devel/release | grep -Eo 'go[0-9]+(\.[0-9]+)+' | sort -V | uniq | tail -1)

if [[ $version == "$release" ]]; then
    echo "latest go release already installed: $release"
    exit 0
fi

release="${release}.linux-amd64.tar.gz"
echo "installing $release"

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

curl -OL https://go.dev/dl/$release
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf $release
rm -rf $tmp

go version

• Hope this script that I made a while ago helps:

cat go-update.sh

#!/usr/bin/bash

function GO_UPD(){
  local GO_VER=$(curl -sk "https://go.dev/VERSION?m=text")
  echo -e " + Installing GO version: ${GO_VER} linux amd64"
  sudo apt install -qq -y golang-go
  wget -q "https://golang.org/dl/${GO_VER}.linux-amd64.tar.gz"
  sudo tar xf "${GO_VER}".linux-amd64.tar.gz -C /usr/local
  [ -f "$HOME/.bashrc" ]&& echo -e "Info: .bashrc exists!\n" || echo -e "Error: .bashrc doesn't exist! Creating... $(> $HOME/.bashrc)\n"
  echo -e '\nexport GOROOT=/usr/local/go\nexport GOPATH=$HOME/go\nexport PATH=$GOPATH/bin:$GOROOT/bin:$PATH' >> $HOME/.bashrc
  source "$HOME"/.bashrc
}
GO_UPD

@theaog Your script is nice and clean. 👏
Since in that release page they also mention about upcoming release, it doesn't work now
(trying to download go1.20.4 which is not yet released at the time of this writing).

A more accurate approach to get the latest release is wget -qO- "https://golang.org/VERSION?m=text"

I did small adjustments to it, so that it matches my setup, having:

• export PATH=$PATH:$HOME/apps/go/bin:$HOME/go/bin
• placed this script in ~/apps/bin

#!/usr/bin/env bash

version=$(go tool dist version)
release=$(wget -qO- "https://golang.org/VERSION?m=text")

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-amd64.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

rm -f ${HOME}/apps/go 2>/dev/null

tar -C ${HOME}/apps -xzf $release_file
rm -rf $tmp

mv ${HOME}/apps/go ${HOME}/apps/$release
ln -sf ${HOME}/apps/$release ${HOME}/apps/go

version=$(go tool dist version)
echo "Now, local Go version is $version"

thank you @dxps, great work!

@theaog Thanks! Although most of the work has been done by you. 😊
One more improvement to it is this version=$(go tool dist version).
Meanwhile, updated the previous post.

@dxps in your modified script you're assuming the GOROOT is $HOME/apps, users might have a different install path.

I think it's best to retrieve the path using go env |grep GOROOT or any other solution you might come up with, as long as it's not hardcoded and servers as many users as possible.

e.g.

goroot=$(go env |grep GOROOT |cut -d'=' -f2 |tr -d '"')
rm -f "$goroot"

@dxps https://gist.github.com/theaog/e8923142320f57d2157dcb28b5cc6b0d

@theaog My preference is to keep different apps installed in $HOMEDIR/apps.
Yes, GOROOT can be considered and this would be more flexibile.

But I think it's misleading to extract the release archive into $GOROOT/go
(as you put it in the script above: sudo tar -C "${goroot//go}").
Currently, GOROOT on my side - with the current version - is /home/dxps/apps/go1.20.4.

But if your recently posted script works, that's the whole point! 👏

Just use go-up project that supports both Linux and MacOS and
automatically determines where to install the new go version based
on the previous one.

Single line solution using curl

curl -sL https://raw.githubusercontent.com/DieTime/go-up/master/go-up.sh | bash

Single line solution using wget

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

I switched to go1.21 version following your prompts , works great!

Unfortunately, that go-up.sh solution doesn't cover some cases.

See a concrete example of how things can be destroyed:

…/apps ❯ curl -sL https://raw.githubusercontent.com/DieTime/go-up/master/go-up.sh | bash
❌ Go not installed, nothing to update
…/apps ❯ 
…/apps ❯ GOBIN=$(which go 2> /dev/null) && echo $GOBIN

windows update?

@SahilDhingraa Plenty of options to consider. As an example, check this out.
