Ubuntu Initial Setup
1. First, we have to install any updates that are pending. At the bottom of your screen, you should notice where it says "Update Manager". Click on that.
2. Now, click on "Install Updates". If you did not see "Update Manager", then skip these two steps.
3. Any time an administrative task is required, you will need to type in your password. This is the same password you used to log in.
Now we wait, this is going to download any necessary security updates to make certain we are using the most current/secure setup possible. This may require downloading hundreds of megabytes. Just go ahead and let it do that, and when everything is downloaded and updated, proceed to the next step. While you wait, Ubuntu may go into screensaver mode. If so, just move the mouse and it will ask you for your password. That will leave screensaver mode.
If the updates are more than a hundred megabytes, it will take quite a while. It may take up to 2-3 hours depending on your computer and internet connection. Nonetheless, this step is critical. Do not skip the updates. Besides ensuring that your setup will be secure, the updates also ensure that all of the applications are up to date and thus most likely to function correctly. Just go ahead and watch a movie for a couple hours, and then return and check on it.
After all of the updates have been downloaded and installed, the "Update Manager" window will now say "Your system is up-to-date" at the top. Further, it will say: "The computer needs to restart to finish installing updates.". Go ahead and press the 'X' in the top right corner of the window, and choose 'Send the shutdown signal". If prompted, click "Shut Down". Once it has fully shut down, the window will disappear and you will be back at the VirtualBox manager. Go ahead and right click on "Primary" and click "Start". This will restart the virtual machine.
If a virtual machine fails to shutdown after 10 minutes or so, then go ahead and close the window again by pressing the 'X' but this time choose "Power down". If it still will not shut down, then VirtualBox may have crashed. If so, just follow these instructions:
( Follow the steps in this mini-section if a virtual machine fails to shutdown, or you need to completely close/restart VirtualBox).
( First, press "Ctrl+Alt+Delete", and then click "Task Manager"). Next, locate the process that is running that starts with "VirtualBox". Right click that process, and click "End Process Tree"
(This should force the window to close).
(Now, restart VirtualBox by going to your start menu, All Programs, Oracle VM VirtualBox VirtualBOx).
Now you will have the VirtualBox manager up again. To restart the Ubuntu machine, simply right click on "Primary" and click "Start".
