Updating Your Linux Distro

Aptitude Package Manager

Command line

aptitude update

Then

aptitude full-upgrade

apt-get and apt-cdrom

apt-get update

Then

apt-get dist-upgrade

add Sudo user

Sudo gives you root access.

adduser <put user name here>

Note do not do this instead replace with user.

Add user to the sudo group.

usermod -aG sudo <user>

To switch to this user

sudo su - <user>

To see which user you are in

whoami

To test protected commands that require sudo (always think twice when you sudo, that you are doing the correct thing. Generally sudo means you are doing something in the core LINUX files needed to make it work. This is why you want a user ID, as it has that extra step requiring you to put sudo in front of the command you want to do. To test this:

Enter command

ls -la /root

You should get a statement back that requires sudo to do this command. If you did not, you missed a step above.

The command you need to enter to see root directory is

sudo ls -la /root

in my version of windows virtual box the screens and commands are slightly different but I got through creating the virtual machine fine, but in adding the DC ROM section, I am not sure which ISO image I should be looking for - should I have an ISO of UBUNTU - I am a little lost here

What choices do you have? You got to mount the virtual CD driving be to iso image (Ubuntu 14 version).
