OSError: [Errno 30] Read-only file system: '/User'. macOS Catalina

Question

I was coding sorter for downloads folder. I'm getting this error, I tried to change permissions:
chmod: Unable to change file mode on Users: Operation not permitted

import os

from_dir = os.path.dirname('/Users/user/Downloads/')
working_dir = os.walk(from_dir)
to_dir = os.path.dirname('/User/user/Downloads/New Folder/')


def move(folder):
    for roots, dirs, files in folder:
        for file in files:
            src_folder = from_dir + '/' + file
            to_folder = to_dir + '/' + file
            if not os.path.exists(to_dir):
                os.makedirs(to_dir)
            os.rename(src_folder, to_folder)


move(working_dir)

Maybe there is another way to write this code just without touching root folders?

Full error:

That error message is bit misleading. In this case, the problem is that there is no /User directory on macOS. The directory is named /Users.

In the following line

to_dir = os.path.dirname('/User/user/Downloads/New Folder/')

User should be Users

to_dir = os.path.dirname('/Users/user/Downloads/New Folder/')

What's happening is that os.mkdirs() is attempting to create a directory User in /. Which is not writable. Which is causing the error message.

To add to the already existing answers: You cannot write to the "input" directory as it is read-only. So you will have to write to Another directory , like the one before the current one.

instead of writing to user/local/current try to right to directory before current which is local in this case.

Just change '/static/' to 'static/' and 'media/' to 'media' in the settings.

You have set writable permission to this folder. Just use in terminal chmod:

chmod -R 777 /absolute/path/to/your/folder

Whatever you are hoping to accomplish, **`chmod 777` is *wrong* and *dangerous.*** You will want to revert to sane permissions ASAP (for your use case, probably `chmod 755`) and if you have had world writable system files on a public-facing system, at the very least investigate whether it could have been breached and used as a pivot point for breaking into your organization’s network. – tripleee Nov 08 '21 at 12:27

Just removed os.path.dirname and it worked.

After I removed os.path.dirname it worked, but not how I was expecting. then trying to fix this, I messed up file system permission and just reinstalled OS. Now it works fine.

So then this is not really an answer to the question. It seems to me that the actual problem was that your file system was mounted read-only (as mentioned in the error message) and reinstalling the OS apparently solved your problem. BTW: reinstalling was overkill, you probably could have changed the mounting options to solve the problem without a complete reinstall. – wovano Jul 26 '20 at 09:48
