I am using raspbian on raspberry pi 3. I recently changed the network interface from this blog. https://learn.adafruit.com/adafruits-raspberry-pi-lesson-3-network-setup/setting-up-wifi-with-occidentalis
I made a mistake by deleting the existing lines of the interface file and replacing it with the contents given in the website.
PROBLEM: My raspberry pi does the booting but it stops at "systemd-hostnamed.service"
Is there any other alternative other than formatting the SD card? I would be grateful if someone could help me with this :)
