Adding Environment variables...

$ echo 'export GOROOT=$HOME/go' >> ~/.bashrc
$ echo 'export GOOS=linux' >> ~/.bashrc
$ echo 'export GOARCH=386' >> ~/.bashrc
$ echo 'export GOBIN=$GOROOT/bin' >> ~/.bashrc
$ echo 'export PATH=$PATH:$GOBIN' >> ~/.bashrc
$ . ~/.bashrc

source /etc/profile
source ~/.bashrc

ALLOWING OTHER USERS TO RUN SUDO

By default, only the user who installed the system is permitted to run sudo. To add more administrators, i. e. users who can run sudo, you have to add these users to the group 'admin' by doing one of the following steps:

sudo adduser username admin

To enable the root account (i.e. set a password) use:

sudo passwd root

Afterwards, edit /etc/sudoers and comment out the line

%admin ALL=(ALL) ALL

to disable sudo access to members of the admin group.
