One of the great things about Linux is its flexibility, something that makes it suitable for a wide range of tasks. This flexibility also means that if anything goes wrong or you need to make a change to the setup of your computer or server, it shouldn't take too long to implement.
Among the most popular Linux distros is Ubuntu, a great alternative to Windows which comes equipped with its own friendly graphical user interface. A wealth of software is available for Ubuntu just as it is for other distros, either via the Ubuntu Software Center, the Synaptic Package Manager or through the Terminal.
From time to time however, downloading and installing software isn't as easy as it should be. Applications might require access to particular software libraries and frameworks, and this is often the case if you receive error messages such as:
error: Cannot find X11 library
Thanks to the flexibility of Linux however, Ubuntu users can reload the x11 library (or any other) within a matter of minutes, enabling a quick resolution.
