Managing user accounts on Ubuntu Linux may involve listing the users on a system, creating a new user, or disabling a user account. Other times, you may need to delete a user account entirely, which is what we'll be covering in this guide.

It's possible to delete a user account from an Ubuntu system via either command line or GUI. The command line method will work on any system, but the GUI method will vary slightly, depending on the desktop environment you're using. In this guide, we'll be showing the process for command line, GNOME, and KDE. This should cover most installations, since GNOME is the default GUI for Ubuntu and KDE the default for Kubuntu. Let's get started.

In this tutorial you will learn:
  • How to remove a user via command line on Ubuntu
  • How to remove a user on GNOME GUI (default Ubuntu desktop)
  • How to remove a user on KDE GUI (default Kubuntu desktop)

  • How to remove, purge, or reinstall Apache web server from Ubuntu

Files with a .rar extension are compressed archives, much like a .tar.gz or .zip file. It's one of many file compression formats that rose to popularity over the years, but requires its own utility to use.

You may have an individual .rar archive such as file.rar, but RAR archives are also known for being split into multiple files, such as file.rar, file.r00, file.r01, etc. In these cases, it's necessary to open the file.rar file, which will then automatically combine the rest of the files into a single archive and extract its contents.

In this guide, we'll see how to extract files from a RAR archive on Ubuntu Linux. This will work whether you have an individual .rar file or an archive that's been split into a sequence of files.

In this tutorial you will learn:
  • How to install unrar utility
  • How to use unrar utility to open rar files

If you ever work with Debian Linux or one of the many Linux distributions that were derived from it, such as Ubuntu, you've probably seen or used the APT package manager. APT is how packages are installed, updated, and removed on such systems.

When using the command line, the apt update and apt upgrade commands can be used to update package repos and upgrade packages, respectively. In this guide, we'll be looking at the difference between the two commands and how they can both be used to upgrade installed packages on a Debian based system.

DID YOU KNOW?
You may also see apt-get update and apt-get upgrade commands used. We've written a full article explaining the difference between apt and apt-get, but suffice it to say that these commands perform basically the same functions as the corresponding apt commands.
In this tutorial you will learn:
  • What distros use apt update and apt upgrade?
  • What is the difference between apt update and apt upgrade?

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

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.
