Hi all,

I have a Rpi 3B+ where I am running Pihole with Unbound. As a secondary DNS, I am planning to use an Odroid HC1 which will also be running other stuff.

Today I installed Armbian_20.05.7_Odroidxu4_buster_current_5.4.50_minimal.img and started the installation of Pihole, which went through just fine.

Then I attempted to install Unbound, but got an error message. The command I run was:

sudo apt install unbound -y

And this is what was returned:

Any idea what I did wrong and how to solve this?

Thanks in advance.

As suggested did you check journalctl -xe for details?

Installing unbound is one things - now you need to configure it - that's why it stops...

probably ipv6 misconfigured, so better play nice and use dns-over-https option.
