11  GUI Runtime Requirements
12  ------------------------

14  The GUI executable, `bitcoin-qt`, is based on the Qt 6 framework and uses the `xcb` QPA (Qt Platform Abstraction) platform plugin
15  to run on X11. Its runtime library dependencies are as follows:
16  - `libfontconfig`
17  - `libfreetype`
18  
19  On Debian, Ubuntu, or their derivatives, you can run the following command to ensure all dependencies are installed:
20  ```sh
21  sudo apt install libfontconfig1 libfreetype6
22  ```
23  
24  On Fedora, run:
25  ```sh
26  sudo dnf install fontconfig freetype
27  ```
