Go, often referred to as Golang, is a statically typed, compiled programming language designed by Google. While it’s known for its performance and efficiency, there might be instances where you need to uninstall it from your Ubuntu system. This could be due to version conflicts, space constraints, or simply because you no longer need it.
In this guide, we’ll walk you through the steps to completely remove Go from your Ubuntu machine.
Let’s get started.
Step 1: Check the Current Go Version
Before uninstalling, it’s a good practice to check the version of Go installed on your system. This can help you verify its presence and location.
go version
Step 2: Locate Go Directories
Go is typically installed in the /usr/local/go directory, but it’s essential to confirm this.
which go
This command will return the path to the Go binary. The parent directory is where Go is installed.
Step 3: Remove Go Directories
Once you’ve identified the Go directory, you can proceed to remove it.
sudo rm -rf /usr/local/go
Step 4: Update the PATH Variable
Go’s binary path is usually added to the $PATH variable. After uninstalling Go, it’s a good idea to remove this path from the $PATH variable.
Edit the ~/.profile or ~/.bashrc file:
nano ~/.profile
Find the line that exports the Go path, something like:
export PATH=$PATH:/usr/local/go/bin
Delete or comment out this line. Save and close the file.
Step 5: Reload the Profile
To apply the changes made to the profile, reload it:
source ~/.profile
