Secondly, please create a file in the home directory named screenshot.sh. And open that's file.
Copy this command in the "screenshot.sh" file:
chvt 7; sleep 5s; DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 xwd -root -out ~/screenshot.xwd; convert ~/screenshot.xwd ~/screenshot.png; rm ~/screenshot.xwd
Save, and type the following command to change the permissions of the screenshot.sh file:
sudo chmod +x screenshot.sh
Next, please logout from your computer until the login menu appears as usual. And go into CLI mode with the keyboard shortcut ctrl + alt + f1 (go to tty1).
Please login into the cli mode, and make sure that you are in the directory of the file screenshot.sh (I suggested on the home because the default of the terminal or cli is in this directory).
to ensure that the file screenshot.sh is in that directory, please type ls and enter. With this command, you can see the list of files and folders in a directory.

But, if not, you can restore to GUI mode with the keyboard shortcut ctrl + alt + f7. And login into the GUI mode. search the screenshot in the directory where you execute the screenshot.sh file. In this case, the result of my screenshot taking is in the home/user directory. As follows:
