I run a Ubuntu virtual machine inside Hyper-V. During the launch, an error appears that failed to start networking.
osis@projmngsys:~$ sudo systemctl status networking

[2]+ Stopped sudo systemctl status networking
Inside sudo nano /etc/network/interfaces
i have:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.69
#netmask 255.255.0.0
#gateway 192.168.1.254
#dns-nameservers 8.8.8.8 8.8.4.4 192.168.1.254
#dns-search google.com
In this regard, the question of how to configure Ubuntu and Hyper-V step by step, so that the Internet and SSH work in it.
