Good catch! This guide was originally written for installation on CentOS 7 and I forgot to remove the section on disabling NetworkManager. For some background, CentOS 8 no longer ships with network-scripts support and requires the use of NetworkManager for network configuration.

You can however run it such that NetworkManager is used for your management interfaces, and network-scripts are used just for the sniffing interfaces.
