sisco311,
It seems that ubuntu works exactly as before after I changed the root permission according to your advice in the recovery mode (is there anythings else I need to do now to be sure ubuntu is fully restored?).
So thank you, and thanks all the other for trying to help (and I also want to thank god I was not listening to their advice )
What other dangers should I be aware of in this respect, and does ubuntu have any option of restoring itself (In my case, I must sudo many times in different ways, and it is impossible not to make simple misprints sometimes)
