In this article, we will guide you through the process of uninstalling Qt5 that was installed from a .run file on Ubuntu. The process involves using the terminal and navigating through the file system.
To uninstall Qt5 that was installed from a .run file on Ubuntu, navigate to the installation directory using the terminal (cd /opt/Qt), run the MaintenanceTool executable (./MaintenanceTool), select the ‘Uninstall only’ checkbox, and follow the on-screen instructions. If you’re unable to find the MaintenanceTool executable, you can use a package manager like apt (sudo apt-get remove qt5-default) or manually remove the Qt binaries and application shortcuts.
Introduction to Qt5
Qt5 is a popular cross-platform application framework used for developing application software with a graphical user interface (GUI). It’s also used for developing non-GUI programs such as command-line tools and consoles for servers.
Sometimes, for a variety of reasons, you may need to uninstall Qt5 from your system. This could be due to compatibility issues, system errors, or simply because you no longer need it.
Locating the Qt5 Installation Directory
The first step in uninstalling Qt5 is to locate its installation directory. This is typically located in the /opt/Qt directory. To navigate to this directory, open your terminal and enter the following command:
cd /opt/QtIn this command, cd stands for “change directory”, which is used to change the current directory in Linux and other Unix-like operating systems. /opt/Qt is the directory where Qt5 is typically installed.
Running the Maintenance Tool
Once you’re in the Qt5 installation directory, you’ll need to run the MaintenanceTool executable. This is a tool provided by Qt that allows you to add or remove components, update existing components, or uninstall the whole software.
To run the Maintenance Tool, use the following command:
./MaintenanceToolThe ./ before MaintenanceTool is used to run an executable file in the current directory.
Uninstalling Qt5
After running the MaintenanceTool, a GUI installer will appear. Look for the ‘Uninstall only’ checkbox at the bottom of the window. By selecting this checkbox, you disable the username and password fields and enable the ‘Next’ button.
Click on the ‘Next’ button to start the uninstallation process and follow the on-screen instructions to complete the uninstallation.
Alternative Methods to Uninstall Qt5
If you’re unable to find the MaintenanceTool executable or face any issues during the uninstallation process, there are alternative methods to remove Qt5:
Using a Package Manager
If you installed Qt5 using a package manager like apt, you can use the package manager’s uninstall command to remove Qt5. For example, on Ubuntu, you can use the following command:
sudo apt-get remove qt5-defaultIn this command, sudo is used to execute the command with root privileges, apt-get is the package handling utility in Ubuntu, remove is the command to remove a package, and qt5-default is the name of the Qt5 package.
Manual Removal
If you installed Qt5 using a .run file and cannot find the MaintenanceTool executable, you can manually remove the Qt binaries and application shortcuts.
Please exercise caution while using the rm command as it permanently deletes files. Always double-check the paths before executing the commands.
