Hi All,

I started a discussion on the matrix channel about some 404 RPM repos and wanted to bring it here to further discuss.
We typically configure our various RPM-based package managers to allow patch updates from the repos.
As an example, if trying to install 5.7.x, can be done as follows:

yum -y install yum-utils
yum-config-manager --add-repo https://rpm.kamailio.org/centos/kamailio.repo
yum-config-manager --disable \*
yum-config-manager --enable kamailio-5.7
yum install kamailio

This will fail though because https://rpm.kamailio.org/centos/7/5.7/5.7/x86_64/ does not exist.
Throughout the repos for centos/rhel/fedora I found the existence of packages is inconsistent.
We can tell the intention was to allow the above behavior as the kamailio.repo comes with the above configuration.
The above example will update /etc/yum.repos.d/kamailio.repo as follows:

[kamailio-5.7]
name=Kamailio - 5.7 - Packages for the latest Kamailio 5.7 release
baseurl=https://rpm.kamailio.org/centos/$releasever/5.7/5.7/$basearch/
enabled=1
metadata_expire=30d
repo_gpgcheck=0
gpgkey=https://rpm.kamailio.org/rpm-pub.key
type=rpm
skip_if_unavailable=True

That is for centos though, and I found that some of the other distros have incomplete kamailio.repo files as well.
In example, the rhel kamailio.repo is missing separate entries for 5.7, but it does exist in the centos version.

Looks like some small cleanup is in order to make the end user experience more consistent.
I believe sergey was maintaining those repos last, please chime in here if you can.
If needed I can pick up some of those responsibilities as well.
