I have a file in a directory with root root permissions. But even with root user I am not able to change the permission or cd to that directory, even not able to change the permissions.

$ lsattr AWS/
$ sudo lsattr AWS/
$


$ sudo chmod 777 AWS/
chmod: changing permissions of 'AWS/': Operation not permitted


$ stat AWS/

    On what kind of filesystem does AWS reside? Could it be mounted read-only? Do you see relevant kernel messages? – berndbausch May 09 '21 at 04:11
