Problem with the installation debian 11

After installing I get this error:

You’re almost there!

You haven’t yet configured your webserver to run RT. You appear to have installed RT’s web interface correctly, but haven’t yet configured your web server to “run” the RT server which powers the web interface. The next step is to edit your webserver’s configuration file to instruct it to use RT’s mod_perl or FastCGI handler.

Do you have a webserver? If so what is your configuration.


Did you install using the Debian packages for RT, or from CPAN?
