This article describes how to install Go in Ubuntu 18 using the snap software and package management tool.
Go is an open source programming language that is quickly growing in popularity. You can discover more about Go at the official website: https://golang.org/
Snap is described as “the app store for Linux”. See my other article getting started with snap for a quick introduction.
How to install Go 1.11.5 in Ubuntu 18 using snap
Snap is included in Ubuntu 18.04.2 LTS so you can start using it straight away.
Step 1: Check if Go is already installed
A common method of verifying if software is installed is to try print the version details. You can do this for Go using the
go version command.
If Go is not installed, you will get an error
Command 'go' not found. Ubuntu also helpfully tells us that we can use snap to install it.
Step 2: Install Go using snap
This section describes how to install the latest stable version of Go using snap. At the time of writing, the latest stable version is Go 1.11.5
You can check the latest available version using
snap info go.
snap info go
Note: the absense of a green check beside the publisher means they are not a verified publisher.

Different versions of the snap are listed as channels.
To install the latest stable version:
sudo snap install go
Alternatively, to specify a version to install, use the
--channel= option, for example
snap install --channel=1.12/candidate go
Step 3: Classic confinement error
At this point you will get an error about classic confinement.
Explanation: Most snaps are installed in confined containers and only have limited access to other system resources. However, snaps published with classic confinement have greater access to the rest of the system, which is desirable for scripting packages such as Go.
Run the install command again, but this time specify the
sudo snap install go --classic
The snap will be downloaded and installed. This may take a few minutes depending on your internet connection.
Step 4: Verify the install
You can verify the snap is successfully installed by using the
list command to list all installed snaps:
go snap will be listed.
go command is now also available for use. Try the
go version command again and this time you should see the Go version details printed:
Now check the go environment details with
An important environmental variable to note here is the
GOPATH which specifies the path of your go workspace. The workspace is a directory where you organise your project source files and binaries. By default it will be set to
$HOME/go. For example, mine is
You can read more about workspaces in the Go documentation: https://golang.org/doc/code.html#Workspaces
You have now successfully installed Go in Ubuntu 18 using snap.

GOPATH and run a simple “Hello, world” program please refer my other article install Go 1.11.5 in Ubuntu 18.
