installing buster 10.5: can't get networking setup

I am installing Bunsenlabs Lithium 2.1 which is a derivative of Buster 10.5. I have been following the instructions that I found at:

https://linuxconfig.org/how-to-setup...n-debian-linux

As suggested, I did the following steps:

1) systemctl stop NetworkManager.service
2) systemctl disable NetworkManager.service
3) Created a /etc/network/interfaces file:

Code:source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

allow-hotplug eno14) Created a /etc/network/interfaces.d/eno1 file

Code:iface eno1 inet static
address 192.168.1.235
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 8.8.8.8 8.8.4.45) ran "service networking restart"

6) ran "ip -a" and got

Code:1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether 5c:26:0a:32:c9:fa brd ff:ff:ff:ff:ff:ffWhen I ran "ip -a", I was expecting the ip address of eno1 to be 192.168.1.235. This is not the case, and I have no connectivity to my router.

Can some one help?
