As a Linux (Ubuntu) user, every time you install an application from a terminal, you will use the apt-get command. Although you can use a graphical interface to install and delete an application, the command line is still considered a powerful method. After installing many large and small applications, you will need more disk space to install other applications, or some programs will no longer work for you. Most people, especially beginners, can install a program from the terminal after reading the materials, but it is difficult to delete it. I used to do this.

Most people, especially beginners, can install a program from the terminal after reading the materials, but it is difficult to delete it. I have also had this experience.
This is a simple tutorial on how to delete installed software packages.
A. Open the terminal (ctrl + alt + t)
B. Input
$ Dpkg -- list
(This command displays all installed packages)
Or
$ Dpkg -- list | less
(In this way, you can easily use the User Key for navigation)
Or
If you know the software package name, you can use the pipeline command grep to find the package and use the following statement:
$ Dpkg -- list | grep-I 'packagename'
Take VLC player as an example.
