I am creating a new machine but I don’t know or it won’t let me configure the machine’s IP address to be static through the dhcp dhclient.conf file. I have returned to eth0 and removed netplan but it still doesn’t work. I don’t know if it should be done this way but I need help.

If it is ParrotOS it might be helpful to check here: https://www.youtube.com/watch?v=WpmpshwnCVc
