Netplan is an utility developed by Canonical, the company behind Ubuntu. It provides a network configuration abstraction over the currently supported two “backend” system, (or “renderer” in Netplan terminology): networkd and NetworkManager. Using Netplan, both physical and virtual network interfaces are configured via yaml files which are translated to configurations compatible with the selected backend.
On Ubuntu 20.04 Netplan replaces the traditional method of configuring network interfaces using the /etc/network/interfaces file; it aims to make things easier and more centralized (the old way of configuring interfaces can still be used: check our article about How to switch back networking to /etc/network/interfaces on Ubuntu 20.04 Focal Fossa Linux). In this article we will learn the basic principles behind the utility, and, just as an example, how we can use it to configure a static IPv4 address for a network interface.
In this tutorial you will learn:
The basic structure of yaml configuration files used by Netplan
How to create a simple rule to assign a static IP to a network interface
How to apply configurations using generate, try and apply subcommands
After installing PHP or an entire LAMP server on Ubuntu Linux, there are a few ways you can check to see what version you're running at any time. This can help you stay up to date and develop web applications that adhere to newer coding standards and conventions, since PHP is still being developed.
In this guide, we'll show you multiple ways to check the version of PHP on Ubuntu. Feel free to pick whichever method is most convenient for your situation.
If there's software on your Ubuntu Linux system that you wish to remove, there are a few ways to go about uninstalling the associated packages.

In this tutorial you will learn:
How to install Redis Server and Client on Ubuntu Linux
How to perform a connection test and configure UFW to allow Redis
Downloading Ubuntu ISO images with a torrent client is one of the most efficient ways to obtain the installation media. Torrenting allows you download the file from multiple sources simultaneously, which means you'll wind up with a very speedy download because the entirety of your network's download bandwidth can remain saturated. It's a very reliable method for downloading large files.
It also takes some strain off of official Ubuntu mirrors, so you're actually helping them out a little by getting an ISO image from the torrent swarm. If you want to continue helping after the download completes, you can choose to leave the Ubuntu torrent in your torrent client and let it "seed" (torrenting jargon for upload) to other prospective downloaders.
Ubuntu is one of the most well known Linux distributions available. You've probably seen Canonical's ubiquitous logo and the familiar look of Ubuntu Desktop running GNOME. What you may not have realized is that Ubuntu also has a very popular server edition of their operating system.
Many distributions choose to concentrate on a single computing environment - either desktop PCs or servers. But Ubuntu's massive popularity and strong footing in the Linux community have allowed it to produce a very viable server edition and still maintain their desktop release.
If you've heard of Linux, you've probably heard of Ubuntu. Out of any distribution, it's likely the most well known. Ubuntu has a solid reputation for being user friendly to newcomers. Couple that with the endless support you'll find online, and you've got an operating system that anyone can pick up and use. For other most popular Linux distributions please visit our dedicated linux download page.
That's not to say that other Linux distributions aren't user friendly. Many are, but there are more than a few that are geared towards power users and system administrators. Ubuntu strikes a nice balance between the two by catering to casual users and still packing the power that enterprises need. Oh, and it's completely free!
Ubuntu is developed by Canonical and has been around since 2004, enough time to gain a strong footing among the greatest distributions. Ubuntu is based on Debian, a true behemoth among Linux distributions that precedes Ubuntu by more than 11 years.
If you're ready to give Ubuntu a shot, there are a few things you should know before downloading it. Ubuntu has a few different editions available and about half a dozen official variations that Canonical dubs "flavors." We'll take a look at all these options below.
The beauty of having your own Minecraft server is that you're totally in charge of your gaming experience. You get to choose what settings are used on the server, you can use (or abuse) your admin powers for an advantage, and bestow those powers on to your fellow gaming buddies. You may want to create a private server for just you and your friends, or make it public for everyone to access.
Ubuntu 20.04 Focal Fossa is a top choice for hosting a Minecraft server, as Linux is known for its stability when running servers and Ubuntu is known for its ease of use. Follow along below as we take you through the steps to get your Minecraft server up and running.
In this tutorial we will be installing PyCharm on Ubuntu 20.04 Focal Fossa Desktop.
WHAT IS PYCHARM? PyCharm is an integrated development environment (IDE) used in computer programming, specifically for the Python language. It provides code analysis, a graphical debugger, an integrated unit tester, integration with version control systems (VCSes), and supports web development with Django as well as Data Science with Anaconda.

Ubuntu is an inherently lightweight operating system, capable of running on some pretty outdated hardware. Canonical (the developers of Ubuntu) even claims that, generally, a machine that can run Windows XP, Vista, Windows 7, or x86 OS X can run Ubuntu 20.04 perfectly fine. Let's take a closer look at the hardware requirements below.
In this tutorial you will learn:
System requirements for Ubuntu 20.04 Desktop
System requirements for virtualized Ubuntu 20.04 Desktop
Conky is a system monitoring program for Linux and BSD that runs on the GUI. It monitors various system resources to report the current usage of CPU, memory, disk storage, temperatures, users logged in, currently playing song, etc. in a sleek little widget on your screen. This way, you're able to see at a quick glance how your computer's components are being utilized.
Conky is lightweight and highly configurable, so you're able to run it without having a negative impact on your system or seeing it stick out like it doesn't belong. We'll show you how to get it installed on Ubuntu 20.04 Focal Fossa and some configuration options to get it looking nice.
