3 Update The System

Now it's time to check for updates and install them. This is done using the Update Manager. Start it by clicking the red exclamation mark on the top bar and selecting Show updates (or start the Update Manager under System > Update Manager):

Click on the Install Now button to install all available updates:

The updates are now being downloaded and installed:

When the update is complete, click on OK (if a new kernel was amongst the updates, a system restart is required to make the changes effective. If this is necessary, you will see a Restart Now button. Click on that button to restart the system.).

The system is now up-to-date.

 

4 Flash Player

If you have checked the Install this third-party software checkbox during installation Flash Player should already be installed on the system.

To check this, open Firefox and type about:plugins in the address bar. Firefox will then list all installed plugins, and it should list the Flash Player (version 11.2 r202) plugins among them.

 

5 Inventory Of What We Have So Far

Now let's browse all menus to see which of our needed applications are already installed:

6 Configure Additional Repositories

First we install gedit. Open a terminal and run:

sudo apt-get install gedit

Some packages are not available in the standard Ubuntu repositories. The easiest way to make such packages available to your system is to add the Medibuntu repository.

Again, open a terminal and edit /etc/apt/sources.list...

sudo gedit /etc/apt/sources.list

..., enable the quantal partner and Ubuntu Extras repositories (if they are not already enabled):

[...]
## Uncomment the following two lines to add software from Canonical's
## 'partner' repository.
## This software is not part of Ubuntu, but is offered by Canonical and the
## respective vendors as a service to Ubuntu users.
deb http://archive.canonical.com/ubuntu quantal partner
deb-src http://archive.canonical.com/ubuntu quantal partner

## This software is not part of Ubuntu, but is offered by third-party
## developers who want to ship their latest software.
deb http://extras.ubuntu.com/ubuntu quantal main
deb-src http://extras.ubuntu.com/ubuntu quantal main

Then save the file.

To enable the Medibuntu repository, please do the following:

Import the repository:

sudo wget http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list --output-document=/etc/apt/sources.list.d/medibuntu.list

Import the gpg-key and update your package-list:

sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update

Then run

sudo update-apt-xapian-index

to make Synaptic display packages from third-party repositories. To make sure you don't get errors concerning the Mint repository, install its keyring next:

sudo apt-get install linuxmint-keyring

Finally install Synaptic:

sudo apt-get install synaptic
