Hello and welcome to the community!

Unfortunately if you have Foreman already installed, you cannot then install Katello.
Foreman and Katello have to be installed together on a fresh instance, rather than one after the other.

Or if it is just a test, try it and hope it works, technically it is possible to do but it is not supported.

Hi Foreman,
As per read your comment, I am understood, firslty of all i will install foreman as well as I need to install katello ,when both are installed after that I will run below comand IN one time to access foreman and katello dashboard in browser.

foreman-installer --scenario katello --foreman-admin-username admin --foreman-admin-password nKCVfRdjfHQZsiLJ

I want to clear about foreman and katello dashoard access ,when above command will run so can I access both dashobased which is foreman dashboard.

Thanks

When you install Katello, it installs Foreman automatically because Katello is a plugin to Foreman and requires Foreman to run. I would recommend following:
