Updating After The Install
Once the install has completed and you have rebooted the computer, you will be greeted by the Ubuntu login screen:
Clicking on your name will make a password box appear:
Type in your password and either press the Enter key or click on the Log In button. After a short wait you wil see the Ubuntu desktop:
At this point I usually just wait for a few minutes. This gives the automatic process that looks for system updates a chance to do its job. There are two types of automatic updates that you will be notified of. The first, and least common, is when there are updates to the proprietary (or restricted) drivers that are available for your system. Ubuntu doesn’t ship with any of these drivers as part of its standard install, but it does look for them when it detects certains types of hardware in your computer. The most common of these is the display driver. All of my computers use NVIDIA graphics cards, and after a couple of minutes on a newly installed system I always see the following notification in the top right corner of my desktop:
If you see this notification, click on the icon at the top left of this image to get the following popup window:
Note that you can display this window at any time by selecting the System >> Administration >> Hardware Drivers menu item. Regardless of how you get there, select the recommended driver and press the Activate button. This will prompt you for your password with the following popup:
Enter your password and press the Authenticate button, then wait for the driver to be installed. Once the installation is complete, the message at the bottom of the Hardware Drivers window will change to tell you need to reboot your system for the change to take effect, as show below:
Press the Close button and reboot your computer. I highly recommend doing this before moving on to the next part of the update. I’ve had problems when combining multiple types of system updates in one reboot, so I always like to do them separately.
The second, and by far the most common, type of system update is when there are updates available for the standard (non-proprietary or unrestricted) software in your system. This includes all of the operating system software as well as any packages that you install later. When there are updates available for this kind of software, and there always are after a fresh install, the following window wil appear:
Note that you can display this window at any time by selecting the System >> Administration >> Update Manager menu item. Regardless of how you get there, if there are updates available, press the Install Updates button. This will prompt you for your password with the following popup:
Enter your password and press the OK button. This will start the download of the updates and display the following window during the process:
Once the download is complete, the updates will be installed while displaying the following window:
When the updates have been installed, the main Update Manager window will be cleared and display a message saying that your system is up to date:
If a reboot is required, the following popup will appear on top of the above window:
If this happens, press the Restart Now button and wait for the system to reboot. If not, press the Close button in the Update Manager window and continue on.
That’s it. You now have a fully installed and updated Ubuntu system.
