How to Download Go 1.18 on Ubuntu
Go is a statically typed, compiled programming language that is designed for building simple, secure, and scalable systems. It has a syntax similar to C, but also features memory safety, garbage collection, concurrency, and a rich standard library. Go is supported by Google and has a large and active community of developers.
Go 1.18 is the latest release of Go that introduces new features such as generics, fuzzing, workspaces, and performance improvements. Generics allow you to write code that can work with different types of data without repeating yourself. Fuzzing is a technique for finding bugs in your code by feeding it random inputs. Workspaces make it easier to work with multiple modules in a single directory. Performance improvements include faster compilation and execution times, especially on ARM64 and PowerPC64 architectures.

$ wget
This will download a file named go1.18.linux-amd64.tar.gz in your current directory. You can check the file size and checksum to verify that the download was successful:
$ ls -lh go1.18.linux-amd64.tar.gz $ sha256sum go1.18.linux-amd64.tar.gz
The file size should be about 130 MB and the checksum should match the one provided on the download page.
Extract the Go archive
The next step is to extract the Go archive into the /usr/local directory, which is where Go binaries are usually installed. You need to remove any previous Go installation before doing this, otherwise you may end up with a broken Go installation. You can use the rm and tar commands to do this:
$ sudo rm -rf /usr/local/go $ sudo tar -C /usr/local -xzf go1.18.linux-amd64.tar.gz
This will delete the /usr/local/go directory and create a new directory named go1.18.linux-amd64 that contains the Go binaries and libraries.
Set up the Go environment variables
The final step is to set up the Go environment variables that will allow you to run Go commands and programs from anywhere on your system. The most important variable is PATH, which tells your shell where to look for executable files. You need to add /usr/local/go/bin to your PATH variable so that you can access the Go binaries. You can do this by editing your /.profile file and appending the following line:
export PATH=$PATH:/usr/local/go/bin
Optionally, you can also set up two other variables: GOPATH and GOROOT. GOPATH is where your Go projects and dependencies are stored. By default, it is set to $HOME/go, but you can change it to any directory you prefer. GOROOT is where your Go installation is located. By default, it is set to /usr/local/go, but you can change it if you installed Go in a different location. You can add these lines to your /.profile file as well:
export GOPATH=$HOME/go export GOROOT=/usr/local/go
After editing your /.profile file, you need to source it or log out and log in again for the changes to take effect:
$ source /.profile
Verify the Go installation
To verify that you have successfully installed Go 1.18 on Ubuntu, you can check the installed version of Go by running the following command:
$ go version go version go1.18 linux/amd64
You can also test your installation by writing and running a simple \"Hello, world\" program. Create a file named hello.go in your current directory and paste the following code:
package main import "fmt" func main() fmt.Println("Hello, world")
Then, run the program by using the go run command:
$ go run hello.go Hello, world
If you see the output \"Hello, world\", congratulations! You have successfully installed and tested Go 1.18 on Ubuntu.

FAQs
Here are some common questions and answers about Go and Ubuntu:
Q: How do I update Go to a newer version?
A: To update Go to a newer version, you need to download and extract the new version of Go as described in this article, and overwrite the existing installation. You may also need to update your environment variables if the new version has a different location or name.
Q: How do I uninstall Go from Ubuntu?
A: To uninstall Go from Ubuntu, you need to remove the /usr/local/go directory and any references to it in your environment variables. You may also want to remove any Go projects or dependencies from your GOPATH directory.
Q: How do I install Go packages or modules?
A: To install Go packages or modules, you can use the go get command, which will download and install them in your GOPATH directory. For example, to install the popular gorilla/mux package for HTTP routing, you can run:
$ go get github.com/gorilla/mux
Q: How do I run Go tests or benchmarks?
A: To run Go tests or benchmarks, you can use the go test command, which will execute any files that end with _test.go in your current directory or package. For example, to run all tests in the current package, you can run:
$ go test
To run benchmarks, you need to add the -bench flag and specify a regular expression that matches the benchmark names. For example, to run all benchmarks in the current package, you can run:
$ go test -bench .
Q: How do I debug Go programs on Ubuntu?
A: To debug Go programs on Ubuntu, you can use the built-in Go debugger, which is called delve. You can install it by running:
$ go get github.com/go-delve/delve/cmd/dlv
Then, you can use the dlv command to start a debugging session for your Go program. For example, to debug the hello.go program, you can run:
$ dlv debug hello.go
This will launch an interactive debugger that allows you to set breakpoints, inspect variables, evaluate expressions, and more. You can find more information about how to use delve on its official website.
