This is a step by step beginner’s guide shows how to install LibreWolf web browser in Ubuntu and its based systems.

LibreWolf is a free and open-source web browser fork from Firefox. The browser focuses on privacy and security, and has uBlocker ad blocker out-of-the-box.

The browser website has an official guide for installing in on Debian and Ubuntu based systems. This tutorial is just a re-write with screenshots and more explanations.

NOTE: This tutorial only works on x86_64 system for modern Intel/AMD CPU architecture types.

Step 1: Install the Key

Adding 3rd party repository in Debian/Ubuntu system needs to first install the key, so your system will trust the packages from that repository.

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command:

wget -qO- https://deb.librewolf.net/keyring.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/librewolf.gpg

This command will download the key file via wget command line tool, dearmor it so the key will be un-readable, finally save it to /etc/apt/keyrings directory.

You may verify the key by running cat /etc/apt/keyrings/librewolf.gpg. And, it should output unreadable text, like the screenshot below shows you.

Step 2: Add LibreWolf Repository

LibreWolf repository so far supports Debian 11/12, Ubuntu 20.04 & 22.04, Linux Mint 20.3, 21.1, 21.2, and all their based systems. It also works in Ubuntu 23.04/23.10 by using the package for 22.04.

1. Get your system code-name

First, run command in terminal (Ctrl+Alt+T) to get the code-name of your system:

lsb_release -sc

The code-name MUST be one of una, bookworm, vanessa, focal, jammy, bullseye, vera, or uma. If NOT, then run command:

cat /etc/os-release

This command will output which version of Ubuntu (and its code-name) is based on.

2. Add LibreWolf repository

Once you got the code-name, run the command below in terminal to create & edit source file:

sudo gedit /etc/apt/sources.list.d/librewolf.sources

Replace gedit in command with gnome-text-editor for Ubuntu 24.04, xed for Cinnamon, pluma for MATE, mousepad for XFCE, or nano command line text editor that works in most desktop environment.

When the file opens, paste the line below and save it:

Types: deb
URIs: https://deb.librewolf.net
Suites: jammy
Components: main
Architectures: amd64
Signed-By: /etc/apt/keyrings/librewolf.gpg

Here you need to replace jammy with the code-name you got in last step. For Ubuntu 24.04 (Noble) and 23.10 (Mantic), just use jammy which is working good in my case.

Finally save the file. For nano text editor, press Ctrl+S to save, then Ctrl+X to exit.

Step 3: Install LibreWolf web browser

After adding the repository and key, run the command below in terminal to refresh your system package cache:

sudo apt update

Finally, install the browser via command:

sudo apt install librewolf

Once successfully installed the package, search for and launch it from start/application menu or ‘Activities’ overview depends on your desktop environment.

And, when a newer version of the browser package is released, just use Software Updater (Update Manager) to update it:

future version of LibreWolf available in Update Manager

Set LibreWolf as default web browser

For the default GNOME Desktop, open Settings (Gnome Control Center), then navigate to Default Applications in left pane. Finally, select “LibreWolf” from the drop-down box for Web.

For GNOME 46 (Ubuntu 24.04), Default Applications has been moved to “Apps” settings page.

Other desktops may have their own option to do the job. If you don’t know where to find the option, try editing the config file that works in most desktop environments. To do so:

• First, open file manager and press Ctrl+H to show all hidden files and folders.
• Navigate to .config sub-folder and click edit mimeapps.list file.
• Finally, set librewolf.desktop for text/html, x-scheme-handler/http, x-scheme-handler/https and save file.

How to Remove LibreWolf Web Browser

To remove the web browser, also open terminal (Ctrl+Alt+T) and run command:

sudo apt remove librewolf --autoremove

Also remove the Key file as well as source repository by running commands in terminal one by one:

sudo rm /etc/apt/sources.list.d/librewolf.sources

sudo rm /etc/apt/keyrings/librewolf.gpg

And, refresh system package cache after making changes to package sources.

That’s all. Enjoy!

This simple tutorial shows how to install brave browser via the new apt source policy in Ubuntu 24.04 & 22.04.

Due to security issue, Debian changed its policy for adding apt sources. Ubuntu is changing the rules too. Since Ubuntu 22.04, it uses more secure key files with digital signature for system repositories and PPAs.

Since Ubuntu 23.10,  it now uses deb822 .sources file instead of the previous .list file for third-party repositories. And, the new source files include ‘Signed-by’ section to specify the key file.

Step 1: Install curl command line download tool

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install curl and apt-transport-https package:

sudo apt install apt-transport-https curl

Type user password (no asterisk feedback) when it asks.

Step 2: Download & Install the key

Then, run curl command to download the key file and save it into /usr/share/keyrings folder.

This can be done by running the single command below in terminal:

sudo curl -fsSLo /usr/share/keyrings/brave-browser-archive-keyring.gpg https://brave-browser-apt-release.s3.brave.com/brave-browser-archive-keyring.gpg

Step 3: Add the brave apt source repository

The previous .list file with or without ‘Signed-By’ is still working! But here I’m going to show the new .sources file.

1. First, run command to create a .sources file under ‘/etc/apt/sources.list.d’:

sudo gedit /etc/apt/sources.list.d/brave-browser-release.sources

Replace gedit with gnome-text-editor for Ubuntu 24.04.

2. Then in the pop-up text editor window, paste following lines:

Types: deb
URIs: https://brave-browser-apt-release.s3.brave.com/
Suites: stable
Components: main
Architectures: amd64
Signed-By: /usr/share/keyrings/brave-browser-archive-keyring.gpg

As you see, the new source file is easy to read, but a bit hard to write for beginners. See this thread for more about it.

Step 4: Update cache & install Brave Browser

After saving the file in last step, you can now run commands below to refresh the system package cache:

sudo apt update

And, finally install the web browser via command:

sudo apt install brave-browser

You don’t have to run the command every time when a new release is out. Just launch “Software Updater”, newer release of the browser package will be available there along with system package updates.

Uninstall Brave:

To remove brave browser package, open terminal (Ctrl+Alt+T) and run command:

sudo apt remove --autoremove brave-browser

And remove the apt source repository by running command:

sudo rm /etc/apt/sources.list.d/brave-browser-release.list

Also remove the key file via command:

sudo rm /usr/share/keyrings/brave-browser-archive-keyring.gpg

Finally, run sudo apt update to refresh system package index.

PHP finally released 8.2.0 release after 7 release candidates. Here are the new features and how to install guide for all current Ubuntu LTS.

PHP 8.2.0 allows to mark a class as readonly, which will add the readonly modifier to every declared property, and prevent the creation of dynamic properties. Moreover, using the AllowDynamicProperties attribute on readonly class will trigger a compile-time error.

Other release highlights in PHP 8.2.0 include:

• Disjunctive Normal Form (DNF) Types
• New stand-alone types: null, false, and true
• New “Random” extension
• Constants in traits
• Deprecate dynamic properties

There are as well numerous bug-fixes and other changes in the release. See the changelog for details.

How to Install Php 8.2 in Ubuntu:

Not recommended for beginners. Only install PHP 8.2 for web developing purpose or there’s specific feature or bug-fix you need in this release.

The popular Ondřej Surý’s PPA has built the package for all current Ubuntu LTS: Ubuntu 18.04, Ubuntu 20.04 and Ubuntu 22.04.

1. First, open terminal or connect to your Ubuntu server and run command to add the PPA:

LC_ALL=C.UTF-8 sudo add-apt-repository ppa:ondrej/php

Run sudo apt install software-properties-common in case the command does not exist. And, type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. Then, install Php packages accordingly. For example, install apache2 module and mysql module via command:

sudo apt install php8.2 libapache2-mod-php8.2 php8.2-mysql

Or install the FPM-CGI binary for use with Nginx:

sudo apt install php8.2 php8.2-fpm php8.2-mysql

For Ubuntu 18.04, run sudo apt update first to refresh package cache.

After installed it, remember to configure your http server (apache 2 or nginx) for the new PHP package, and configure php8.2 via files under ‘/etc/php/8.2/’.

Uninstall Php 8.2

To remove the package, simply run command:

sudo apt remove --autoremove php8.2 libapache2-mod-php8.2 php8.2-*

And remove the Ubuntu PPA via command:

sudo add-apt-repository --remove ppa:ondrej/php

Remember Midori? The lightweight web browser that was default in Elementary OS and Bodhi Linux revived!

Midori was a popular lightweight web browser used the WebKitGTK rendering engine and GTK UI toolkit. The development of the project was however discontinued more than 3 years ago. And, Ubuntu even removed it from system repository since Ubuntu 22.04 LTS.

According to the Wikipedia, the Midori project has been merged with the Astian Foundation in 2019. And, Astian announced a week ago that Midori browser is still alive!

It’s now Chromium based web browser that using Electron and React with both desktop edition for Linux, macOS, and Windows, and mobile edition for Android.

The browser still aims to be lightweight, fast and free. It’s still an open-source app, with the source code host in gitlab project page. (update: the project page does no longer exist! If you know where Astian hosts the source code, please leave comment below.)

Midori web browser next generation

The new Midori browser so far features:

• New logo.
• Adblock integration, block ads out-of-the-box.
• Incognito mode support.
• Chromium based, without Google services and low resources usage
• Fast and highly customizable UI.
• Partial Chrome extensions support.
• To use its own open-source AstianGO search engine. Though, it so far uses DuckDuckGo as default. While Google, Bing, and Ecosia available for choice.

How to Install New Midori web browser in Ubuntu & other Linux

Astian offers official Midori packages for Linux through AppImage and .deb package.

Option 1: AppImage

AppImage is a portable package format without installation required. Just select download it from its website:
