The problem is on this line in ipautil.CheckedIPAddress with the
netmask=ifdata['netmask'] call
ifnet = netaddr.IPNetwork('{addr}/{netmask}'.format(
addr=ifaddr,
netmask=ifdata['netmask']
))
On my CentOS 7.3 box which has python-netifaces-0.10.4-3.el7.x86_64 it works
On my CentOS 7.4 box where I am trying to install ipa-server-4.5.0-22.el7.centos.x86_64
and it has python2-netifaces-0.10.5-2.el7_4.x86_64 installed, it fails with:
ValueError: IPAddress() does not support netmasks or subnet prefixes! See documentation
for details.
So I don't see how anyone has been able to install ipa-server on a RedHat 7.4 or
CentOS 7.4 box
