Hi
I could use a little help restoring my network on my Debian10/mint installation. The system says eth0 unknown device. in etc / network / interface it says: allow-hotplug enp9s4 iface enp9s4 inet dhcp.
ifconfig finds no network device.
Someone who has an idea of what I can try
Thanks in advance

Hi Musa,

Do you also use the Network Manager?

BTW, enp9s4 isn’t correct in your /etc/network/interfaces (see your output of ifconfig -a).
