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"

I have sketched a simple script to automate the task:

git clone https://github.com/udhos/update-golang
cd update-golang
sudo ./update-golang.sh

Thanks @udhos! That script worked perfectly!

Thank you @nikhita for sharing and @udhos for the script.

@udhos thanks so much 👍

You are awesome# @nikhita !
Thank you

why its still showing as 1.6.2 after running script? am i doing something wrong?

Thanks @udhos

Will the script work on windows7 as well? pls confirm..

@akkida746 No, it's a bash script. It is not compatible with Windows' shell

@udhos it works like a charm!

@udhos thanks a lot!!

Nice

thanks @udhos works perfectly on my linux box

thanks udhos, script worked flawlessly on mac

@saifiifazal I have the same problem.
It's showing the old version even after running the script.
Here is a screenshot.

Remove your previous install first?

apt-get purge golang-go
rm -rvf /usr/local/go/

Remove any mention of go in e.g. your ~/.bashrc and then do command

whereis go

@udhos Script worked perfectly

@udhos your script works perfec. Thanks!

@udhos thanks for script

@udhos Thanks for the script!

Thank you @nikhita and @udhos !

Thanks for this gist. It's funny ! after completing all the tasks you find the script of the first comment. It would be nice if it was included directly in the gist. Thank you.

There's no need to delete the old copy. You can just overwrite it. Here's a one-liner that should work for Linux and MacOS:

curl --silent https://storage.googleapis.com/golang/$(curl --silent https://golang.org/doc/devel/release.html | grep -Eo 'go[0-9]+(\.[0-9]+)+' | sort -V | uniq | tail -1).$(uname -s | tr '[:upper:]' '[:lower:]')-$(case "$(uname -m)" in i*) echo '386' ;; x*) echo 'amd64' ;; *) echo 'armv61'; esac).tar.gz  | sudo tar -vxz --strip-components 1 -C $(dirname $(dirname $(which go)))

It always grabs the latest version and overwrites whatever is in your path (based on which go). I've only tested it on Linux since that's all I have access to. Let me know if you have any issues with it and I'll fix it.

PS. Here's a multi-line more verbose version:

release=$(curl --silent https://golang.org/doc/devel/release.html | grep -Eo 'go[0-9]+(\.[0-9]+)+' | sort -V | uniq | tail -1)
os=$(uname -s | tr '[:upper:]' '[:lower:]')
arch=$(case "$(uname -m)" in i*) echo '386' ;; x*) echo 'amd64' ;; *) echo 'armv61'; esac)

curl --silent https://storage.googleapis.com/golang/$release.$os-$arch.tar.gz \
  | sudo tar -vxz --strip-components 1 -C $(dirname $(dirname $(which go)))

brew upgrade go

@fabienthetis real mvp

brew upgrade go

Did the job, thanks!
I was trying to tweak @fearphage one-liner. Because my mac (sierra 10.12.6) does not support the -V sort option!
Then I saw @fabienthetis comment!!!!!
So K.I.S.S.

Thanks a ton!

Thanks !

Awesome!

git clone https://github.com/udhos/update-golang
cd update-golang
sudo ./update-golang.sh

@udhos Its Works in Centos. Good and Thanks

@udhos Thanks, work perfect!

@udhos, really great. Thanks!

@udhos, Thank you very much!

Alternative, when you don't mind having multiple different versions:

go get golang.org/dl/go1.12.4
go1.12.4 download
go1.12.4 version

The one-liner provided by @fearphage worked perfectly for me! ^__^

@fearphage It works for me on Ubuntu 18.04. Thank you so much.
