In this guide, we'll walk you through the process of installing FreeCAD on Ubuntu 24.04 using Flatpak. FreeCAD is a powerful, open-source parametric 3D modeling software that's particularly useful for mechanical engineering and product design.

Why Use Flatpak?

Flatpak is a next-generation technology for building and distributing desktop applications on Linux. It offers several advantages:

• Consistent runtime environment across different Linux distributions
• Sandboxed applications for improved security
• Easy updates and rollbacks
• Access to a wide range of up-to-date applications

Installation Steps

We'll break this process down into three main steps: installing Flatpak, adding the Flathub repository, and finally installing FreeCAD.

Step 1: Install Flatpak

First, we need to install Flatpak on your Ubuntu system. Open a terminal and run the following command:

sudo apt install flatpak

Step 2: Add Flathub Repository

Next, we'll add the Flathub repository, which hosts a large collection of Flatpak applications:

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

Step 3: Install FreeCAD

Now that we have Flatpak set up, we can install FreeCAD:

sudo flatpak install flathub org.freecadweb.FreeCAD

During the installation, you may be prompted to confirm the installation. Type 'y' and press Enter when asked.

Launching FreeCAD

After installation, you can launch FreeCAD from your application menu or by running the following command in the terminal:

flatpak run org.freecadweb.FreeCAD

Troubleshooting Tips

If you encounter any issues during the installation or while using FreeCAD, consider the following:

• Ensure your system is up to date by running sudo apt update && sudo apt upgrade before installation
• If FreeCAD doesn't launch, try restarting your computer to ensure all Flatpak changes are applied
• Check the FreeCAD forums or documentation for specific error messages you might encounter
