I do not know what happens...but in my laptop, all folders and files have user www-data instead of root.
in directory /desktop /music ....alll directories ..
how can I change user root?
I use command
chown -R www-data:root /
chown -R root:www-data /
any ideas?? I tried a lot but I am not able to change the user for files and directories.
even I tried lots of commands but I do not know how can I change user as root
