#Sudo apt get update options install

When you run this command, you’ll see the information being retrieved from various servers. Updating the package database requires superuser privileges, so you’ll need to use sudo. In fact, this is the first command you need to run on any Debian-based Linux system after a fresh install. If you don’t update this database, the system won’t know if there are newer packages available or not. Update the package database with apt-getĪpt-get basically works on a database of available packages. It’s better to have an understanding of it so that you can handle your Linux system in a slightly better way. I am using Linux Mint in this tutorial, but you can use any other Ubuntu-based Linux distribution, such as elementary OS, Linux Lite, etc. Read this article to learn more details about apt and apt-get commands. There is also a newer apt command on the scene which is a simpler version of apt-get. You will see all of these commands with examples later in this guide. apt-get is for installing, upgrading, and cleaning packages, while apt-cache command is used for finding new packages. There are two main tools around APT: apt-get and apt-cache.

#Sudo apt get update options install

You can use it to find and install new packages, upgrade packages, clean your packages, etc. There are already dpkg commands to manage it, but apt is a more user-friendly way to handle packages. This way, you don’t have to build a program from the source code.ĪPT (Advanced Package Tool) is the command-line tool to interact with this packaging system. A packaging system is a way to provide programs and applications for installation. I guess you already know that Ubuntu is derived from Debian Linux. This makes managing packages easier on Debian-based distros. The apt-get is a set of command line tools that allow you to install, remove and update deb packages installed via the APT (Advanced Package Tool) in Debian and Ubuntu. In this guide for beginners, I am going to explain various of apt-get commands with examples so that you can use them like an expert Linux user. Now, you might be aware of a few apt-get commands and their usage, but you might not know some others. In fact, first on the list of things to do after installing Ubuntu is to use apt-get update and apt-get upgrade. Let's have a look at its syntax through some realistic case studies of this mechanism.If you have started using Ubuntu or any Ubuntu-based Linux distribution, such as Linux Mint, elementary OS, etc., you must have come across the apt-get command by now. It also gives the name of the distribution (usually Stable, Testing, Unstable or Experimental for the standard distributions provided by Debian) together with its version (for example, 11 for Debian Bullseye). It specifies the origin (usually “Debian” for the packages of official mirrors, but it can also be a person's or an organization's name for third-party repositories).

Every package source is identified by the information contained in a Release file that APT downloads together with the Packages files. The available selection criteria include the package's name and the source providing it. If several generic entries exist, the first match is used. When APT checks /etc/apt/preferences and /etc/apt/preferences.d/, it first takes into account the most specific entries (often those specifying the concerned package), then the more generic ones (including, for example, all the packages of a distribution).
