I am using an Oracle Linux 8.5 iso that has the anaconda installer (anaconda 33.16.5.6-1.0.1e18) . I need to change the default prompt text at the end of a successful install. I tried to install the anaconda source code anaconda-33.16.5.6-1.0.1.el8.src.rpm, I had some issue with dependency which I resolved later but still getting the following error:-
dnf install anaconda-33.16.5.6-1.0.1.el8.src.rpm
Latest Unbreakable Enterprise Kernel Release 6 38 kB/s | 3.0 kB 00:00
Error: Will not install a source rpm package (anaconda-33.16.5.6-1.0.1.el8.src)
Could you please advise me on what it is needed in order to change the prompt text at the end of a successful install.

The above image shows the default text at the end of a successful install which I need to changes.
Thank you for your help in advance
