Why I'm giving message `A start job is running for raise network interfaces` at boot after disabling predictable network interfaces names?

Solved by changing file /etc/network/interfaces.d/setup from:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

to:

auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp

Disable the service that waits to start the network interfaces.

systemctl disable NetworkManager-wait-online.service

And to enable:

systemctl enable NetworkManager-wait-online.service

Alternatively you can reduce the amount of time that it waits to start the job.

vim /etc/systemd/system/network-online.target.wants/networking.service 

TimeoutStartSec=5min ##Change parameter, should be at the end of the page.
