I just have deleted some file of the operating system and I have access just from the terminal. Everything else is disappeared. Last think I did it was a the installation of a python interpreter. Is it likely to have some source list deleted. I dont know whether I can restore my system.
I dont know how to access my internet connection from the termial. So I cannot update or upgrade anything.
Another thing is that whatever I write on my terminal it doesn't appear but it remains invisible. So I should be careful what I type in otherwise I will make thing worse. In same cases I cant even see any feedback from my terminal This is even more confusing.
Is there any way out how to restore it a day before unless there is any other way more efficient
Thank you in advance
