I followed the steps to install hassbian on my pi2. After i booted I configured my wpa_supplicant.conf file and rebooted. I get an error that says dhcpcd cant start which I don’t think I need that so I disabled it with systemctl cmd and rebooted.
I get an error that says cant raise network interface ( something like that). I then plugged in a network cable and rebooted. Same error.
I my interface file has the following
auto eth0
iface eth0 inet dhcp
allow-hotplug wlan0
auto wlan0
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface wlan0 inet dhcp
