Error with installer - Permission denied

[RHS-Code]

After I've copied the files to the correct directory and tried to open the installer, but it told me Permission denied. I set the Permissions for every file and directory having to do with it to 777 but it's still telling me permission denied. (I've also tried several browsers)

That user and group look wrong. Try running a chmod -R <user>: ., replacing <user> with the webserver user.

Changed the user and group, still the same error (your command didn't work I've used chown -R <user>:<group> <path>

Try this : chown -R www-data:www-data

Thank you it worked.
