"Permission Denied" as root when moving files

Using sudo on the RPISEC-MBE virtual machine, I have mounted and copied my files that were on a USB flash drive to an admin folder (that I have access to). Unfortunately, even with sudo I can't seem to copy them to the /levels/lecture directory. Why is it not letting me copy those files in, even as root?

gameadmin@warzone:~$ mkdir /media/usb ; sudo mount /dev/sdb1 /media/usb
gameadmin@warzone:~$ ls -l /media/usb/rpisec

drwxr-xr-x  2  root  root  16384  Jun  7  15:41  crackme
gameadmin@warzone:~$ sudo cp -R /media/usb/rpisec/* /home/gameadmin/

Solution 1:

From the documentation:

The warzone marks many files as immutable to prevent users from changing them and ruining the game for other players. For example, we don't want the lab2B user to delete its .pass file or /levels files. A few system files, such as /etc/passwd, are also marked immutable.

If you would like to modify or delete these files simply remove the immutable flag: chattr -i filename

We recommend that you add the flag back when you are done making your changes: chattr +i filename

File immutability is a wonderful thing in many circumstances. If you have the opportunity, learning how to use these can save you a lot of headache later 👍🏻
