It seems like you are trying to change the permissions of a file or directory, but the file system is read-only, which means that you cannot make any changes to it.

If you need to modify the file or directory, you will need to remount the file system as read-write. You can do this by running the following command:

sudo mount -o remount,rw /media/root/F498-910E

After running this command, you should be able to change the permissions of the file or directory using the `chmod` command.
