With its intuitive interface and extensive brush library, MyPaint has become a popular choice among digital artists using Linux systems. In this comprehensive guide, we’ll walk you through the process of installing MyPaint on Ubuntu 24.04 LTS, also known as Noble Numbat.

What is MyPaint?

MyPaint is a free, open-source graphics application designed specifically for digital painting and drawing. It offers a wide range of features that cater to both beginners and experienced artists:

• Intuitive and customizable interface

Originally developed for Linux, MyPaint has evolved to become a versatile tool for digital artists across various operating systems. Its simplicity and focus on the painting experience make it an excellent choice for Ubuntu users looking to explore digital art.

System Requirements

Before we begin the installation process, ensure that your system meets the following requirements:

• Ubuntu 24.04 LTS (Noble Numbat) installed and updated
• At least 2GB of RAM (4GB or more recommended for larger canvases)
• 1GB of free disk space
• A graphics tablet (optional, but recommended for the best experience)

It’s also a good idea to have a stable internet connection for downloading the necessary packages.

Preparation Steps

Before installing MyPaint, it’s essential to prepare your system to ensure a smooth installation process.

Updating the System

Open a terminal window and run the following commands to update your system:

sudo apt update
sudo apt upgrade

This will ensure that all your existing packages are up to date, reducing the likelihood of conflicts during the installation.

Checking for Existing Installations

If you’ve previously installed MyPaint, it’s a good idea to check its status:

dpkg -s mypaint

If MyPaint is already installed, consider removing it before proceeding with a fresh installation:

sudo apt remove mypaint

Backing Up Important Data

While installing MyPaint shouldn’t affect your existing data, it’s always a good practice to back up important files before making system changes.

Installation Methods

There are several methods to install MyPaint on Ubuntu 24.04 LTS. We’ll cover three popular approaches: using Ubuntu’s default repository, using Flatpak, and building from source.

Method 1: Using Ubuntu’s Default Repository

This is the simplest and most straightforward method for installing MyPaint.

1. Open a terminal window.
2. Run the following command to install MyPaint:

   sudo apt install mypaint

3. Enter your password when prompted.
4. Wait for the installation to complete.

This method ensures that you get a version of MyPaint that’s compatible with your Ubuntu system. However, it may not always be the latest version available.

Troubleshooting

If you encounter any issues during installation, try the following:

• Ensure your system is up to date by running sudo apt update && sudo apt upgrade
• Check for any conflicting packages or dependencies
• Verify that you have sufficient disk space

Method 2: Using Flatpak

Flatpak is a universal package management system that allows you to install applications across different Linux distributions. This method often provides access to more recent versions of software.

1. If Flatpak is not already installed on your system, install it:

   sudo apt install flatpak

2. Add the Flathub repository:

   flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

3. Install MyPaint using Flatpak:

   flatpak install flathub org.mypaint.MyPaint

4. Follow the prompts to complete the installation.

Using Flatpak can provide a more up-to-date version of MyPaint, but it may consume more disk space due to its containerized nature.

Pros and Cons of Flatpak

Pros:

• Access to the latest versions
• Consistent experience across different Linux distributions
• Sandboxed applications for improved security

Cons:

• Larger installation size
• Potential integration issues with system themes
• May require additional setup for accessing system resources

Method 3: Building from Source

For users who want the latest features or need to customize their installation, building MyPaint from source is an option. This method requires more technical knowledge but offers the most control over the installation.

1. Install the necessary build dependencies:

   sudo apt install git python3-pip python3-dev libgirepository1.0-dev libgtk-3-dev

2. Clone the MyPaint repository:

   git clone https://github.com/mypaint/mypaint.git

3. Navigate to the cloned directory:

   cd mypaint

4. Install Python dependencies:

   pip3 install -r requirements.txt

5. Build and install MyPaint:

   python3 setup.py build
   sudo python3 setup.py install

Building from source allows you to access the latest development version of MyPaint and customize the build process. However, it requires more time and technical expertise.

Advantages and Challenges

Advantages:

• Access to the latest features and bug fixes
• Ability to customize the build
• Better understanding of the software’s structure

Challenges:

• More complex installation process
• Requires knowledge of build tools and dependencies
• May introduce compatibility issues with system libraries
