Readonly file and can't change permissions

There is a file with read only permissions, but even root can't chmod it.



Permissions of the file: -rw-r--r--



After trying to chmod 777:



chmod: changing permissions of ‘motd’: Operation not permitted


I'm doing it from the root account. How is it possible to lock a file like this?

    lsattr /etc/motd and check if the immutable bit is set. You will see an i in the output if it is.
