Ubuntu cannot create a new folder

When creating a new folder in Ubuntu, there is a problem that it cannot be created. The reason is that there are no permissions, “you are not the owner, so you cannot change these permissions.”

Directly log in with root or open the file manager with root authority, that is, input sudo Nautilus in the terminal to solve the problem.
