Final answer:
To uninstall an app in Ubuntu 20.04 using the terminal, you can open the terminal (Ctrl+Alt+T) and use the command 'sudo apt remove package_name', replacing 'package_name' with the name of the app you wish to uninstall. You can also use 'dpkg' with 'sudo dpkg --remove package_name' for precise removal.
Step-by-step explanation:
To uninstall an app in Ubuntu 20.04 using the terminal, you can use the apt or dpkg package management tools. Here is an example of how you can uninstall an app using the terminal:
- First, open the terminal. You can do this by pressing Ctrl+Alt+T on your keyboard or by searching for 'Terminal' in the Ubuntu application menu.
- Once the terminal is open, you need to type the command sudo apt remove followed by the package name. For example, if you want to uninstall the app named 'example_app', you would type sudo apt remove example_app.
- After pressing Enter, you'll be prompted to enter your password. Type it in and press Enter again.
- If the package was found, apt will tell you which packages will be removed. Confirm the removal by typing 'Y' and pressing Enter.
- The app will then be uninstalled from your system.
Alternatively, if you know the exact package name, you can use dpkg with sudo dpkg --remove package_name. Make sure to replace 'package_name' with the actual name of the package you want to uninstall.
If you want to remove the app as well as its configuration files, you might use sudo apt purge package_name instead of remove.
