2.1. step 2

dnf upgrade https://yum.theforeman.org/releases/3.19/el9/x86_64/foreman-release.rpm \
https://yum.theforeman.org/katello/4.21/katello/el9/x86_64/katello-repos-latest.rpm

Describe the issue

2.1. step 2 fails everytime i do this procedure

dnf upgrade https://yum.theforeman.org/releases/3.19/el9/x86_64/foreman-release.rpm \
https://yum.theforeman.org/katello/4.21/katello/el9/x86_64/katello-repos-latest.rpm
...
Public key for foreman-release.rpm is not installed
Public key for katello-repos-latest.rpm is not installed
Error: GPG check FAILED

I then have to edit the line

dnf --nogpgcheck upgrade https://yum.theforeman.org/releases/3.19/el9/x86_64/foreman-release.rpm https://yum.theforeman.org/katello/4.21/katello/el9/x86_64/katello-repos-latest.rpm

Anything else to add? (context, suggestions for a fix, etc.)

I also think all these lines should have sudo on them for ease of copying and be inline with current security guide lines but not necessary.
