This comment is demeaning, and insulting. As best I can tell, it is *intended* to be demeaning and insulting.
Please don't assume you know why I wrote that comment. I absolutely did not write that comment to demean or insult anyone. Anyway, so that anyone else who may experience this issue wants to know the resolution, I will post here. At least there is a record of it then. The URL is stated as "HTTPS://packages.networkradius.com/freeradius-3.0/centos/7/" No matter what I tried I could only ever get it to list 3.0.23. So, I thought, well, may as well try http rather than https and, with using the following two commands it worked: "yum list freeradius-3.0.22*" - it listed back "freeradius-3.0.22-1.el7" "yum install freeradius-3.0.22-1.el7" radiusd -X shows no issues and the version is "3.0.22". At least that clears up the confusion, but not sure why http worked and https did not - maybe a security issue or certs. Anyway, thank you Matthew and Alan for the pointers. I will keep those in mind for future reference. A basic resolution but sometimes the basics are easily missed.
