Hi I am trying to install OTRS on a linux server and when I call the installer from the browser I get this error message

Warning: Kernel/Config.pm isn't writable!

Comment:

If you want to use the installer, set the Kernel/Config.pm writable for the werserver user! Can't open /opt/otrs/Kernel/Config.pm: Permission denied

Please help me, I need to try OTRS.
