Pi router with pihole - internet from wifi, routed to ethernet

[Nickie_emp]

I am helping someone who still has the issue as per

Network manager breaks pi-hole

The issue I am facing: DNS service not running and FTL offline Details about my system: Pi3B+ Raspbian Buster (10) What I have changed since installing Pi-hole: I need to make network manager working for EAP wifi to be working properly. After installing network manager, the only way for it to work is to sudo apt purge dhcpcd5. I believe though that pi-hole can't work without it. Is there any other way?
