I think I may have accidently deleted the sddm. I am a sort of beginner at linux, getting through linux by watching tutorials and videos online. Please help me out.
The system was running fine after I removed and reinstalled python3-apt as per one of the tutorials online.
But when I booted again onto kubuntu, the system shows only the tty1-tty6 screens.
I have dual booted the system with Windows 10.
