Very first I would like to show my present os Version.

$  cat /etc/os-release 

In the above image, you can see Kali Linux 2020.4 is installed. First update your existing OS, to avoid unnecessary errors.

$  sudo apt update && sudo apt full-upgrade -y  

Moving further, let us add the kali Linux official repository for 2021.1.

$  echo "deb http://http.kali.org/kali kali-rolling main non-free contrib" | sudo tee /etc/apt/sources.list 

To update the repositories you need to edit the sources.list file. The command mentioned above will help you to update the Kali Linux 2021.1 repositories.

Now run the command to update the Kali Linux.

$  sudo apt update && sudo apt full-upgrade -y 

In between the update process, you will get a package configuration prompt. Simply press the tab Button, it will highlight the "OK", and hit enter.

Now press the left arrow key on your keyboard to highlight "Yes" and hit enter.

After the completion of the update, once again hit the normal update and upgrade command.

$  sudo apt-get update && sydo apt-get upgrade 

Kali Linux is up to date to its latest version 2021.1. Now let me remove the Gedit text editor and configure the "command not found utility". To configure the "command not found utility" they the commands in the terminal written below.

$  nano ~/.zshrc 

# enable command-not-found if installed
if [ -f /etc/zsh_command_not_found ]; then
    . /etc/zsh_command_not_found
fi

Now reboot the Kali Linux.

$  sudo reboot -f 

Welcome back. Now Search for the MATE terminal and open it.

Now create a text file by using the touch command and edit it using gedit.

$  touch testfile.txt 

$  gedit testfile.txt 

Here you can see Kali has detected that the Gedit program is not installed and it is asking to install so that you can view and edit the text file. Basically "no command found is a utility that corrects our spelling mistakes in the terminal and provides us the easy to assess commands without searching on google.
