Trouble installing Go correctly on Ubuntu

Question

I successfully installed this on my Mac, just having trouble on Linux. I'm following along their doc https://golang.org/doc/install. I'm running a 64bit machine so I downloaded the 64bit archive. Once downloaded I run

sudo tar -C /usr/local/ -xzf ~/Downloads/go1.4.2.linux-amd64.tar.gz

I created a go directory in my home folder. I have the structure

/home
--/chrism
----/go
------/src
------/pkg
------/bin

And I add the following to /etc/profile. After saving I run source /etc/profile

export PATH=$PATH:/usr/local/go/bin
export GOPATH=$HOME/go

In src/ I added a directory git.mycompany.com and in their another directory called test. In test/ I made test.go and pasted the block of code from the tutorial above in

package main

import "fmt"

func main() {
    fmt.Printf("hello, world\n")
}

When I run go run test.go, it outputs the following

chrism@ubuntu:~/go/src/git.mycompany.com/test$ go run test.go 
# fmt
Usage: pack op file.a [name....]
Where op is one of cprtx optionally followed by v for verbose output.
For compatibility with old Go build environments the op string grc is
accepted as a synonym for c.

For more information, run
    godoc cmd/pack
# runtime
Usage: pack op file.a [name....]
Where op is one of cprtx optionally followed by v for verbose output.

    godoc cmd/pack

If I add more packages to my import statement, it'll output the documentation for all those packages as well.

EDIT 0: I also tried to install with apt-get. I uninstalled and removed my previous changes and then installed. This resulted in the following when running:

chrism@ubuntu:~/go/src/git.mycompany.com/test$ go run test.go 
go build fmt: exec: "/usr/local/go/pkg/tool/linux_amd64/pack": stat /usr/local/go/pkg/tool/linux_amd64/pack: no such file or directory
go build runtime: exec: "/usr/local/go/pkg/tool/linux_amd64/pack": stat /usr/local/go/pkg/tool/linux_amd64/pack: no such file or directory

EDIT 1: This is the output of running go env

GOROOT="/usr/lib/go"
GOBIN=""
GOARCH="amd64"
GOCHAR="6"
GOOS="linux"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOTOOLDIR="/usr/lib/go/pkg/tool/linux_amd64"
GOGCCFLAGS="-g -O2 -fPIC -m64 -pthread"

These are the steps I followed for installing Go in my Ubuntu system :

Short Version : 1. Run following commands for installation:

sudo apt-get remove -y gccgo-go && wget http://golang.org/dl/go1.8.linux-amd64.tar.gz && sudo apt-get -y install gcc && sudo tar -C /usr/local -xzf go1.8.2.linux-amd64.tar.gz && echo "export PATH=\$PATH:/usr/local/go/bin" >> ~/.bashrc

Note: Changes the version number to install a specific version of Go. For example, to install 1.9 instead of 1.8 change the file name to go1.9.linux-amd64.tar.gz. The latest Go distributions can always be found at the official Go downloads page

2. Setup workplace. (Point 6)

Long Version:

1. Download the binary release from here. Use go x.x.x.linux-amd64.tar.gz for ubuntu. For version 1.4.2 you can type following in terminal.

   wget http://golang.org/dl/go1.8.linux-amd64.tar.gz
   

2. Install gcc for cgo

   sudo apt-get install gcc 
   

3. Extract the tarball in /usr/local. It should create a go directory.

   tar -C /usr/local -xzf go1.8.linux-amd64.tar.gz
   

   (Typically these commands must be run as root or through sudo.)

4. Add /usr/local/go/bin to the PATH environment variable.

   gksu gedit ~/.bashrc
   

5. Add following line in the end of file

   export PATH=$PATH:/usr/local/go/bin
   

6. Setup Workspace

   a. Create a workspace directory name go in your preferred location (unless you are using the default go installation location). I am using /home/vembu/work/projects/go

   mkdir -p /home/vembu/work/projects/go
   

   b. Export GOPATH

   gedit ~/.bashrc
   

   c. Add following line in the second last line

   export GOPATH=/home/vembu/work/projects/go
   

   d. For convenience, add the workspace's bin subdirectory to your PATH:

   export PATH=/usr/local/go/bin:$PATH:$GOPATH/bin
   

   e. Finally .bashrc’s last two line should look like this

   export GOPATH=/home/vembu/work/projects/go
   export PATH=/usr/local/go/bin:$GOPATH/bin:$PATH
   

   f. Restart terminal.
