/etc/network/interfaces. FAILED. What to do?

Question

linux

When configuring /etc/network/interfaces.

# The loopback....
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static 
address 192.168.1.100 
netmask 255.255.255.0 
gateway 192.168.1.1
dns-nameservers  8.8.8.8

after reloading the service > /etc/init.d/networking restart
gives an error > journalctl -xe
BUT IF REMOVE auto eth0 . That is overloaded with norms and the error does not climb out.
Help me to understand

Answer 1

Why are you sure that your interface is called "eth0"?
On systemd systems, interfaces are named like enp1s0 and so on. - if you do not take measures to return the old names. (by adding a config to Grub or rules.d).
Show us the output of "ip a"
PS For posting code and error texts, you should use the "code" tag
