In the first method, you need to open the Ubuntu Software Center, go to the "installed" section, select the software you want to delete, and click on "remove". In the second method, you need to install the Synaptic Package Manager through the command line, search for the software you want to delete, right-click on it, select "Mark for Complete Removal", apply the changes, and then click on "Apply". In the third method, you can use the command line with the syntax "sudo apt-get remove package_name" or "sudo apt-get --purge remove package_name" to delete the software.
