Have you run the following command:

PIHOLE_SKIP_OS_CHECK=true sudo -E pihole -up

I use Cloudflare DoH on my Pi. I block DNS over port 53 on my firewall for most of my devices. My pfSense box does DoT itself.

The SKIP_OS_CHECK command did the trick. Thank you too!

It worked! Didn't bother trying it the first time based on a previous post, and because I figured it was an update glitch.

Thank you, and sorry for wasting your time.

That's the only way you'll be able to install from here on out then.
