@anon55913113 I get the exact same error as @kkorkky in the first post of this thread:
Error: Unable to get latest release location from GitHub
Doing a nslookup on any domain gives me:
connection timed out; no servers could be reached
I believe I'm gonna give up on getting a Pi-Hole running on my network for now and wait until a fix is released so it works on initial install. Thanks anyway!
