sudo apt-get remove --purge python3*
and it just remove many things from system, including the ubuntu-desktop. After that, I reinstalled the desktop with the command:
sudo apt-get install ubuntu-desktop
The problem is that, when I open a terminal, it shows me a

What's wrong and how can I correct this?
