If you are new to xubuntu and you probably didn't know how to install and uninstall program/software on xubuntu, this short tutorial might help you. I'm going to show you how to install and uninstall on xubuntu.
How to install and uninstall program using graphical mode
To install and uninstall using graphical interface, you can use tool named 'Software' or 'Software Center' on xubuntu, this graphical tool is available out of the box when you install xubuntu. You can open 'Software' or 'Software Center' from xubuntu start menu and then select 'Software'.
Once opened you will see three tabs, 'all', 'installed', and 'updates', the 'all' tab will list all available program, you can also search program if you know the name. The 'installed' tab, just like the name, it will list all software/program that currently installed.
Lastly the 'updates' tab is where you can see list of new updates for software that's currently installed. If a program/software is currently not installed then there will be 'install' button, but if a program is currently installed then there will be 'remove' button for uninstalling it.
Important to note that, 'Software' or 'Software Center' will not display command line based program, so you only can install graphical based program with it. If you want to install command line based program then you need to do it from the terminal.
How to install and uninstall program using command line mode
Installing and uninstalling program/software can be done under command line/text mode/terminal, in fact it is the common way people installing software on linux, i think every body who use linux should definitely learn command line.
To install you can use command 'sudo apt-get install' followed by the name of the software package, and for uninstall you can use command 'sudo apt-get remove' followed by the name of the software package. Here's an example:
Install using command line
sudo apt-get install [program name]
example:
sudo apt-get install vlc
sudo apt-get install gedit
Uninstall using command line
sudo apt-get remove [program name]
example:
sudo apt-get remove vlc
sudo apt-get remove gedit
NOTE: you can replace the 'apt-get' command with just 'apt', it's a different command line tool but works exactly the same.
