These versions should work:
[root@server ~]# rpm -qa nethserver-squidguard ufdbGuard
ufdbGuard-1.34.6-2.el7.x86_64
nethserver-squidguard-1.9.2-1.7.g186a20a.ns7.noarch
Please try the installation again:
yum clean all
yum install --enablerepo=nethserver-testing,epel-testing nethserver-squidguard ufdbGuard
If there’s an error move away the conflicting file. @geofxgt please move away /etc/sysconfig/ufdbguard before install.
Maybe you need to remove first:
yum remove nethserver-squidguard ufdbGuard
