The installation of packages and applications on Linux has left something to be a very complicated time. With the wide popularization of the Desktop Linux distributions install applications on your operating system is a task junk. The wide range of applications found ready to install (more than 20,000 in ubuntu, debian and derivatives) can make the user experience in tiring having to meet and select the correct package. Even with the use of automatic verification of dependency, the user should be aware of what to install and learn the correct way to look, or you can simply explore the archives and discover incredible applications. In this text I will present the most correct way to make installation of applications in Ubuntu, Debian and derivatives, as of the graphics mode or debian type packages. Deb. This is the most suitable for both novice user as intermediary.
For example we will install two packages found in an official repository and one distributed by third parties. To use the package from the repository that is accessible by Synaptic menu "System" -> "Administration" -> "Synaptic Package Manager." To access and use the Synaptic it must be done with the user created during installation of Ubuntu, is another case, this user should be in the group admin. Before the opening of Synaptic is requested the user's password (if required administrative tasks), as Figure 1.

On the main screen of Synaptic (Figure 2) we have some important functions, which together are the steps we must follow to make any intalação. Must first click "Reload" which is the update of the list of available packages in the repositories configured (it is assumed here that the main repositories are already qualified and that the user is connected to Internet). Then click "Search" and in the search window (Figure 3) tell one or more search terms (usually the name of the application) can also determine the type of filter to be applied only in the research endeavor in the "Name" of the package, in "Description and Name" and other options that may be selected under the search term informed.
Figure 3: Screen Search of Synaptic
Usually the search in the description of the package behind a larger set of results. After finding and identifying the package want to mark it for installation (Figure 4). Depending on the package may be the need for installation of dependencies, this is checked and are proposed for installation as shown in Figure 5, just click "Flag" to confirm the installation of the dependencies of the package previously selected.

Figure 5: Marking dependencies required for installation
After all selected packages desired click "Apply" and wait for the download and installation of packages and their dependencies, Figures 6 and 7 respectively.

Figure 7: Installation of packages downloaded from repositories
Another way to install packages. Deb in graphics mode is when the package is not available in official repositories but is distributed by other means. With the package file. Deb stored on the disk of your machine, click the right mouse button on it and select "Open with gdebi Installer Package" (Figure 8), or just click the package that the manager will open automatically . On the screen of the installer package gdebi (Figure 9) you can check the details of the package and other information, click the "Install Package" to perform the installation. Also in the use of Synaptic will be requested the user's password (for administrative purposes). The installation of this form also notes the need for installation of facilities, if any and the package is not needed in the repository, the installation will be effective only after the resolution of all dependencies.

fuck it then uninstall .. With so many dependencies .. and dependencies of dependencies in ubuntu ... you never have control of that or not installed. What is useful or not the system. Though I like the idea of having a repository always be available.
Have control over the system is important ... but I would never comply with large installations of Windows that can take over time (. Net, Corel Draw, etc.) and at deinstalação is instantaneous. It would be possible? course not! A quick search for the file system and the registry of windows, just to find much trash that often leaves the system very unstable because of the substitution of inadivertida dlls.
But each system has a philosophy, Ubuntu and other Linux, some prefer to keep things dried, so the dependencies and more dependencies (programs with dynamically linked libraries), but in compensation the performance of the system is shown in the use of Linux in various mobile devices and complete domination in the market for sub-notebooks nowadays, where 4GB of disk are more than sufficient for the system and the programs used by the vast majority of users.
