Windows emulation application

Wine lets you run Windows software on other operating systems (like Linux). You have to note that not every application will run, but users tested and reviewed more thousands applications. Application database has more than 13,000 entries with applications that work on various OSes.

Updating your Operating System

This operation can be done using two methods. First you can use the Update Manager (which can be find under System –> Administration.

After you press the Check button you will be prompted for your user session password. After this step, if any updates available, you can install them, all or partially based on your selection.

The other method can achieve the same result using the command prompt terminal. Terminal can be found under Applications –> Accessories.

In the terminal you can type:

sudo apt-get update
sudo apt-get upgrade

The apt-get command is a powerful command-line tool used to work with Ubuntu’s Advanced Packaging Tool (APT) performing such functions as installation of new software packages, upgrade of existing software packages, updating of the package list index, and even upgrading the entire Ubuntu system.

First command updates the package index; the APT package index is essentially a database of available packages from the repositories defined in the /etc/apt/sources.list file.
Second command upgrades packages; from time to time, updated versions of some packages currently installed on your computer become available from the package repositories.

The sudo command will run the commands as super user and you’ll be prompted for your user session password. After the system update you can run sudo apt-get autoclean to clear out the local repository of retrieved package files. More details about apt-get command can be found if you ran in a terminal the command man apt-get.
