I recently tried to install OpenVPN on my pi. Since then I've been having trouble with the networking in my Pi. I already removed it and purged it.
I can ssh into my Pi fine (my home network is in perfect condition). But when I try to ping Google it says
ping: unknown host google.com Also, whenever I try to use the internet some other way I can't do anything.
How can I solve this? What do I need to do to make a diagnostic?
