How To: Add Ubuntu’s Default Repositories

The headline is correct that, in today’s article, I’ll explain how to add Ubuntu’s default repositories – in the terminal. Seeing as I’m doing so, I’ll tell you about each repository as we go along. They exist for different reasons, so we might as well know how and why.

This article is probably only interesting to new Ubuntu users who want to learn to do things in the terminal. That’s a lofty goal, though I’ve already explained how to reset Ubuntu’s default repositories – but that’s graphical. It’s also likely quicker to do this in a GUI. Still, we might as well cover this. 

I see no reason to make the intro section very long. The article will be plenty long. So, onto the article!

Add Ubuntu’s Default Repositories:

Yup. You guessed it. You’re going  to need an open terminal. Many of my articles do. If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open.

You’re also going to need Ubuntu, or an official Ubuntu flavor. I can’t recommend trying this will all Ubuntu derivatives, as I have not ever tested this in all Ubuntu derivative. So, only do this if you are using Ubuntu or an official flavor of Ubuntu – or it may mess up your system. You  have been warned.

About Repositories:

If we’re going to be writing about repositories, allow me to explain what those are. They’re central points from which you download software and software upgrades. They are there to provide the software you need, though not all software is included.

There’s generally a lot of software in them and some folks will only install software included in their default repositories. (Some folks will refuse even some software in the available repos, as the repositories may vary based on the licenses used by the software within.)

Ubuntu’s Main Repository:

Inside this repository, you’ll come across all the software the system needs to have a running system and a bunch of applications. All the software in this repository is FOSS (Free Open Source Software).

You already have this repository enabled, but stuff happens. If you’ve somehow disabled it (don’t do that) you can add it back with:

Ubuntu’s Universe Repository:

This repository contains software that is also FOSS – but Ubuntu can’t vouch for the update state or software inside the Universe repository. They are packages managed by the community, not by Ubuntu themselves.

It’s software you can install and doesn’t really come with all that many risks as the above may sound. Stuff tends to get updated pretty well. There are a lot of diligent people who tend to this sort of stuff. Upgrades are usually fairly rapid. To enable Ubuntu’s Universe repository, you’d run this command:

Ubuntu’s Multiverse Repository:

 In Ubuntu’s Multiverse repository, you’ll find software that is not FOSS. Due to licensing reasons, the folks behind Ubuntu can not maintain any of this software.

The software gets updated, but nothing in this archive is going to have Ubuntu doing so. Ubuntu also can’t ship this repository as enabled by default. To enable the Multiverse Repository, use this command:

Ubuntu’s Restricted Repository:

In Ubuntu’s Restricted repository, you’ll also have software that is not FOSS. The Multiverse repository contains things like drivers for hardware that doesn’t have FOSS drivers available. Well, the Restricted repository is where drivers exist.

A number of people are sticklers for FOSS-only operating systems. plus there’s the licenses to worry about, mean that these end up in a repository all there own. If you’re using hardware that doesn’t have FOSS drivers, you might need the Multiverse repository. To enable the Multiverse repository, you’ll want to use this:

Ubuntu’s Partner Repository:

In Ubuntu’s Partner repository, it’s still software that doesn’t have a FOSS license. It’s Ubuntu adding the software for partners of Ubuntu. It’s useless and will be axed at some point. (It has been empty in recent Ubuntu iterations.)

So, you can forget about this one. I will explain how to enable the Partner repository, as it’s both obvious and I’m pretty sure it’s still a thing on older versions of Ubuntu, and the LTS variants are going to be around for a while longer. It’s easy to enable Ubuntu’s Partner repository, the command is simply:


Well, there you have it. You have another article and this one tells you to add Ubuntu’s default repositories. There’s a GUI way to do so, but this one takes place in the terminal. Besides, I already showed you how to do it graphically. This article almost got missed. I was at a funeral and that took a bunch of time and energy. But, I just couldn’t resist keeping up the same publication schedule.

Let’s Install ‘gedit’ With All The Fixin’s In Ubuntu

This article is going to tell you how to install gedit along with a bunch of plugins. There are many text editors out there, but gedit is a popular choice. Many plugins exist to extend gedit, and this is an easy way to install a bunch at once.

Notes: This will only install the plugins in the default repositories. This article covers just Ubuntu, but will likely work with derivatives and even Debian.

gedit, the default editor for the Gnome desktop environment, is a part of the GNOME Core Applications and is available in almost every distro, at least every major distro. The gedit text editor doesn’t need a lot of additional dependencies, which helps make it useful on almost any desktop environment.

You can use gedit for anything – from programming, to writing markup for your website. You can use it just like you would any other plain text editor. There are many ways to extend it, to add functionality not included by default, and that is with plugins.

There are plugins to highlight syntax, to auto-complete words, to auto-close brackets, etc. You can make gedit do all sorts of things you’d not expect from a plain text editor. 

Disk space is absurdly cheap these days, so I don’t see any reason to not install as many plugins as I can, and no reason to not do it all at once. I may not use them all, but I’ll use many of them and I can just not enable those that I don’t want to use. I may have a reason to use them later on. You never know!

Well, this article will help you install gedit and all the plugins your system can find!

Install gedit With Plugins:

Like always, you need an open terminal and you can do that with your keyboard by pressing CTRL + ALT + T and enter the following:

What’s going on with that command? You can string together requests with apt, and this is installing gedit first, then a pack of common plugins, and then every other plugin that uses the ‘gedit-plugin-*’ format. It checks for all software with that naming pattern and installs them if they’re not already installed and have satisfied dependencies.

By the way, the asterisk is known as a wildcard. A wildcard basically means, “any character.” So, foo* is anything from fool to foolish, and foob* is anything from foobar to foob-gibberish or whatever. 

It should be noted that this only installs the plugins. You still can’t use them until after you enable them. To enable them, you need to open ‘gedit’ (which will almost certainly be called “Text Editor” in your menu) and click on preferences, where you can navigate to the right-most tab and enable them as needed. It looks like this:

gedit preferences
Select plugins ’til you’re satisfied!

Anyhow, if you did this properly,  you will now have a bunch of plugins enabled. Is this a bit of overkill? Perhaps, but disk space is cheap and the entire thing takes up less than 19 additional MB on my system. You might as well do it all at once. 


And there you have it. You now have gedit installed along with a bunch of gedit plugins. It’s really not all that difficult and there’s no real huge hit on performance or resources. Heck, it doesn’t even take all that long!
