I have been trying to install unbound on a fresh headless raspbian buster setup after installing Adguard Home in it. I already tried with the latest PiHole and it worked great. That is why I did a fresh raspbian buster install and then installed Adguard home and installed unbound after that.
Every time I run sudo apt install unbound I get the following error:

I reformatted my SD Card 3 times. First time I disabled IPV6 and assumed it caused the error.
2nd time I created a new user and thought that was the problem. Third time I left everything untouched and just installed Adguard on it and still I got this error.
I didn't get this error when I installed Unbound after installing PiHole v5. Can anyone tell me how I can fix this issue?
