I am trying to setup a static IP for my Raspberry Pi 4 (Raspbian GNU/Linux 10 buster, connected to the router via an ethernet cable) that is running OMV (5.6.3-1) according to the "Conquer the Command Line" by Richard Smedley. It describes to modify the /etc/dhcpcd.conf file, but when I try to see the contents of the file with
cat /etc/dhcpcd.conf
I get an error saying that this file does not exist. Is there another way to setup a static IP (all the methods I have found on the Interner use this file)? Or am I looking in the wrong place?
