Easily Install & Manage Gnome Extensions in Ubuntu 22.04 via This App

Trying out different Gnome Extensions frequently? The new “Extension Manager” app is really a good choice to make life easier!

We usually install extensions by browsing through the Gnome Extension website and using the on page on/off switch. Then, manage the settings via a separate ‘Extensions’ app. However, Ubuntu’s pre-installed Firefox does not support the process since it’s a Snap package.

Without installing anther browser package and opening the site time by time, a new project “Extension Manager” has been created as an “App Center” for Gnome Extensions.

Manage installed extensions

The app integrates an “Installed” tab to enable, disable, remove extensions and manage their settings, just like “Extensions” app does.

In the “Browse” tab, it allows to search extensions with “Popularity”, “Downloads”, “Recent” and “Name” filters. And, it provides button to install extensions directly from search results that are compatible with your Gnome edition.

Search and install extensions

Like Ubuntu Software (or Gnome Software), user may view the details about an extension in a separate page with screenshot, description, supported Gnome versions, and reviews.

Install the Extension Manager in Ubuntu & Other Linux

For Ubuntu 22.04, press Ctrl+Alt+T on keyboard to open terminal. When it opens, paste the command below and hit run to install the package:

sudo apt install gnome-shell-extension-manager

Run sudo apt update to refresh package cache on a brand new system in case the command does not work.

After that, you may click the top-left “Activities”, then search for and open the application:

For old Ubuntu releases and other Linux, the application is available to install as universal Flatpak package. Do the setup first, and then install the package from Flathub page (Run the bottom command).

How to Remove Extension manager

For any reason, you may remove the extension manager by opening terminal and run command:

sudo apt remove --autoremove gnome-shell-extension-manager

If you installed it via the Flatpak package, use this command instead to remove it:

flatpak uninstall --delete-data com.mattjakeman.ExtensionManager

And remove useless libraries via flatpak uninstall --unused.

How to Create USB Installer for Windows 7/8/10 in Ubuntu 22.04 Linux

Want to create an USB installer for Microsoft Windows, but only has a Linux PC (or server)? Here’s how to do the trick in Ubuntu, Arch, Fedora, and their based systems, e.g., Linux Mint, Manjaro.


Today when I was installing Windows 7 on my 10 years old laptop, the first I tried is booting the ISO image via Ventoy USB stick. Sadly, it just didn’t boot!

So, I turned to WoeUSB-ng. It’s a free open-source tool to create a Windows USB stick installer from a real Windows DVD or iso image.

It’s a rewrite of WoeUSB in Python programming language with graphical interface support! With it, you can burn Windows Vista, Windows 7, Window 8.x, Windows 10 and Windows PE into USB with following boot mode:

  • Legacy/MBR-style/IBM PC compatible bootmode
  • Native UEFI boot for Windows 7 and later (FAT file-system only).

Step 1: Install WoeUSB-ng

Arch Linux users just need to run yay -S woeusb-ng command in terminal to install the app.

1.) Install Dependency

Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run the command below to install the dependencies:

sudo apt install git p7zip-full python3-pip python3-wxgtk4.0 grub2-common grub-pc-bin

Type user password for sudo authentication, though there’s no asterisk feedback

For Fedora, run the command below instead:

sudo dnf install git p7zip p7zip-plugins python3-pip python3-wxpython4

2.) Install WoeUSB-ng

As a Python application, it’s easy to install via the pip package manager. To do so, just run command:

sudo pip3 install WoeUSB-ng

Once installed, click the top-left “Activities” button, then search for and open the tool:

Step 2: Create Windows USB Installer via WoeUSB-ng

Firstly, you need to download the Windows ISO image or insert the CD/DVD drive, plug in your USB stick (8GB+ is recommended).

Then, launch WoeUSB-ng from start menu, select your ISO image or CD/DVD drive and highlight the USB stick (click “Refresh”) if not in list.

Before clicking the “Install” button, backup your data in the USB stick. It by default formats the drive into FAT, though you can select “NTFS” in options.

After clicking “Install” and confirm in pop-up dialog, it will open a new small dialog indicates the installing process.

If everything goes OK, it should prompt “Installation Succeed” when done. Plug the USB stick in target machine and select boot it in BIOS or UEFI, and enjoy!

Create USB Windows Installer from command line

Running Linux without a desktop session? The tool also has command line options to do the job.

Firstly, find out the USB stick device name (usually /dev/sdb) via command:

sudo fdisk -l

Then, run the command to create installer from iso image (run woeusb -h to get more options):

sudo woeusb --device /PATH/TO/ISO /dev/sdb

And for BIOS boot, it’s better to add ‘–workaround-bios-boot-flag’ to workaround BIOS bug that won’t include the device in boot menu.

Uninstall WoeUSB-ng

To remove the application, open terminal and run the command:

sudo pip3 uninstall WoeUSB-ng

Then clear the shortcut icon via command:

sudo rm /usr/share/applications/WoeUSB-ng.desktop
