How To Install and Run Qt-Designer for Python on Ubuntu

Ubuntu 12

In this article, we will walk you through the step-by-step process of installing and running Qt Designer for Python on Ubuntu.

Quick Answer

To install and run Qt Designer for Python on Ubuntu, you need to update your system, install PyQt5 and development tools, and launch Qt Designer using the "designer-qt5" command.


Qt Designer is a powerful tool that allows you to design Graphical User Interfaces (GUIs) without writing any code. It is a part of PyQt5, a set of Python bindings for the Qt libraries which can be used to create cross-platform applications.


Before we begin, ensure that you have a working Ubuntu system and that you have administrative access to install packages.

Step 1: Update Your System

First, it’s always a good idea to update your system before installing new software. Open your terminal and run the following command:

sudo apt-get update

This command fetches the latest list of packages from the repositories, ensuring you get the latest version of PyQt5 and Qt Designer.

Step 2: Install PyQt5 and Development Tools

Next, we install PyQt5 and the necessary development tools. Run the following command:

sudo apt-get install python-pyqt5 qttools5-dev-tools

Here’s what this command does:

  • sudo: This command gives you administrative privileges (required to install packages).
  • apt-get install: This command installs new packages.
  • python-pyqt5: This is the package for PyQt5, which includes Qt Designer.
  • qttools5-dev-tools: This package includes additional development tools for Qt.

If you’re using a different version of Python, such as Python 3, replace python-pyqt5 with python3-pyqt5.

Step 3: Launch Qt Designer

Once the installation is complete, you can launch Qt Designer. Run the following command:


This command opens the Qt Designer application.

Alternatively, you can find Qt Designer in your system’s application launcher or start menu.


In this article, we’ve shown you how to install and run Qt Designer for Python on Ubuntu. With this tool, you can design GUIs for your Python applications without writing any code. Remember to replace python-pyqt5 with python3-pyqt5 if you’re using Python 3.

For more information on using Qt Designer, refer to the official PyQt5 documentation.
