New PPA for Installing Transmission 4.0.0 in Ubuntu 22.04 | 20.04 | 22.10

The Transmission BitTorrent client released version 4.0.0 a few days ago. Here’s PPA repository contains the package for Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10, Linux Mint 21/20.

According to the release note, transmission 4.0 features new C++ and gtkmm code-base, with much less CPU and memory usage than before. It also adds support for using BitTorrent v2 and hybrid torrents, support for IPv6 blocklists, and more.

How to Install Transmission 4.0.0 via Ubuntu PPA

I’ve built the new release packages into this unofficial PPA for Ubuntu 20.04 and higher. Ubuntu 18.04 is not supported due to dependency library version mis-match.

The new web user interface depends on NPM (Node.js package manager). It requires internet connection while building process, but launchpad build farm does NOT have. Meaning so far the PPA package does not include new web UI via JavaScript, but the old web user interface for remote control is stilling working in my case in Ubuntu 22.04.

1. First, press Ctrl+Alt+T on keyboard to open a terminal window. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/transmission

Type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. After adding the PPA, you can then launch Software Updater (Update Manager) and upgrade the system pre-installed transmission package to the new 4.0.0 release.

For Ubuntu based system without the BitTorrent client pre-installed, you may run command below to install it:

sudo apt update && sudo apt install transmission-gtk

You may replace transmission-gtk with (or add) following package:

  • transmission-qt – Qt user interface for KDE, LXQt, etc.
  • transmission-cli – command line interface.
  • transmission-daemon – the daemon for running in background, and access via webUI

Uninstall Transmission 4.0.0

You can choose to downgrade the BitTorrent client to system pre-installed version, by running command in terminal:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/transmission

Or, remove the software packages instead by running command:

sudo apt remove --autoremove transmission-gtk transmission-qt transmission-cli transmission-daemon

And remove the PPA repository either via “Software & Updates” tool by removing the source line under “Other Software” tab, or by running command:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/transmission

That’s all. Enjoy!

Wine 8.0 Stable Released! How to Install in Ubuntu 22.04 | 22.10

Wine, the compatibility layer for running MS Windows apps in Linux and macOS, announced new stable 8.0 release after 1 year of development.

Wine 8.0 has finally completed PE conversion. All modules can be built in PE format. Meaning various features to be supported, such as copy protection, 32-bit applications on 64-bit hosts, Windows debuggers, x86 applications on ARM, etc.

Wow64 (Microsoft’s subsystem for running 32 bit applications on 64-bit Windows) is implemented for essentially all Unix libraries. Once the legacy calls removed, it will be possible to run 32-bit Windows applications on Linux without any 32-bit Wine libraries.

Other changes in Wine 8.0 include:

  • Print Processor architecture implemented.
  • Enable light theme for configuration by default.
  • Convert the graphics drivers to run on the Unix side of the syscall boundary.
  • Effects are supported in Direct2D.
  • Direct3D improved with more graphics cards support.
  • Greatly improved the controller hotplug support.
  • Support Sony DualShock and DualSense controllers when the hidraw backend is used.
  • Introduce Windows.Gaming.Input API with hotplug notifications, force feedback effects and haptics, as well as trigger rumble support.
  • Mono engine updated to 7.4.0

How to Install Wine 8.0 in Ubuntu and Linux Mint

Winehq website now has a good tutorial teaching about how to install Wine packages in Ubuntu based systems. And, here is a re-write with more descriptions.

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

sudo dpkg --add-architecture i386

This command makes it possible to install 32-bit packages in 64-bit Ubuntu, since Wine at the moment still requires a lot of 32-bit libraries.

2. Then, run command in terminal to create “keyrings” folder under ‘/etc/apt’ directory for storing the keys. With -p flag, it ignores error if that folder already exist.

sudo mkdir -p /etc/apt/keyrings

3. Next, use wget command line downloader to download the GPG key for winehq repository, and store in the folder you created in last step.

sudo wget -O /etc/apt/keyrings/winehq-archive.key

4. Now, run command to download the config file for Winehq apt repository and store in ‘/etc/apt/sources.list.d/’.

sudo wget -NP /etc/apt/sources.list.d/$(lsb_release -sc)/winehq-$(lsb_release -sc).sources

IMPORTANT: This command is for Ubuntu 22.10, 22.04, 20.04, 18.04 only! For Linux Mint, Zorin OS, etc, you have to replace the “$(lsb_release -sc)” in command with the codename of Ubuntu version your system is based on:

  • For Ubuntu 22.10 based system, use kinetic.
  • For Ubuntu 22.04 based system (e.g., Linux Mint 21), use jammy instead.
  • For Ubuntu 20.04 based (e.g., Zorin OS 16.x), use focal.
  • For Ubuntu 18.04 based system, use bionic

5. After setting up the Wine’s official apt repository, run the command below to fetch package index:

sudo apt update

In the output, there should be a output line indicates Get x xxxxx InRelease.

6. Finally, install Wine stable 8.0, as well as dependency libraries via command:

sudo apt install --install-recommends winehq-stable

7. After successfully installed Wine packages, run command to generate the config files and open the configuration dialog.


There you can verify Wine version and change the settings of this layer.

8 Finally, right-click on your EXE file in file manager and select “Open With Wine Windows Program Loader” (or select it from open with other applications dialog). See if Wine supports your Windows app.

How to Remove Wine 8.0

To remove the software package as well as dependency libraries, simply open terminal and run command:

sudo apt remove --autoremove winehq-stable

Also, remove the Wine apt repository by removing the source file:

sudo rm /etc/apt/sources.list.d/winehq-*.sources

And remove the key file via:

sudo rm /etc/apt/keyrings/winehq-archive.key

Finally, remember to refresh package index via sudo apt update command.

How to Compile & Install Pinta 2.1 from Source in Ubuntu 22.04 |22.10

For Pinta users who do NOT like the Snap and Flatpak packages that run in sandbox. Here’s how to build the 2.1 release from source tarball in Ubuntu 22.04 & 22.10.

Pinta has switch to .NET 6.0 framework since version 2.0. Which however needs internet connection to fetch something for the first time during the build time. And, most Linux so far still has Pinta v1.x in their system repositories.

Thankfully, building Pinta 2.1 from source is not hard. And, here’s the step by step guide show you how!

1. Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install .NET 6 as well as dev libraries for building the package.

sudo apt install dotnet-sdk-6.0 debhelper autotools-dev autoconf-archive gettext intltool libgtk-3-dev

NOTE: If you’ve already installed dotnet 7.0 from Microsoft repository, skip dotnet-sdk-6.0 in command.

2. Next, download the source tarball from github release page (under ‘Assets’ section):

3. Then, extract the tarball in file manager. Right-click on source folder and select “Open in Terminal”.

4. The last step will open a terminal window and automatically navigate to the Pinta source folder as working directory.

In the terminal window, run command to configure the source:


And, finally compile and install it via:

sudo make install

NOTE: This step needs internet connection if you’re first time using dotnet to build a package. And, it may fail if you’ve ever installed .NET 7.0 but removed (not completely) and use .NET 6.0 now.

If everything’s done without any error, you should now be able to search for and launch Pinta from system start menu (‘Activities’ overview).


Until you remove the source folder, you can run sudo make uninstall at any time from in that folder to uninstall Pinta package.

If you’ve removed the source folder, re-do the previous steps and replace the last command with sudo make uninstall.

[Quick Tip] How to Disable Event Sound in Ubuntu 22.04 | 22.10

Ubuntu by default play a short alert sound when you plug in/out USB drive, power supply, or hit tab function key in terminal.

This is useful for indicating certain type of system messages and events, but it’s easy to mute these type of sounds in case you don’t like them. And, here’s the quick tutorial show you how.

Single command to disable event sound

There’s a dconf database option to toggle on/off this feature for GNOME and Cinnamon desktop.

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

gsettings set org.gnome.desktop.sound event-sounds false

Not only for Ubuntu, this command should also work for Fedora workstation, Debian, Arch and other Linux with GNOME desktop.

For Linux Mint cinnamon desktop, use the command below instead:

gsettings set org.cinnamon.desktop.sound event-sounds false

Disable event sound via Dconf Editor (graphical way)

In case for those who hate Linux commands, there’s an advanced configuration tool Dconf Editor, that provides a graphical interface to do the job.

1. Firstly, search for and install Dconf Editor from Ubuntu Software (or your system package manager).

2. Then launch Dconf Editor, and navigate to org/gnome/desktop/sounds. Finally, turn off the option for ‘event-sounds’.

Similarly, navigate to org/cinnamon/desktop/sounds or org/mate/desktop/sounds and set the key depends on your desktop environment.

That’s all. Enjoy!
