Supervised Debian 11 installation


After the SSD of my Home Assistant installation died, I am reinstalling on an old machine I had lying around. I followed these guidelines for a supervised install on Debian 11. Everything works like a charm, except for the last step (the home assistant installation).

Relevant output:

[info] Restarting NetworkManager
[info] Restarting docker service

[info] Install supervisor Docker container
Error response from daemon: Get "": dial tcp: lookup on [::1]:53: read udp [::1]:43041->[::1]:53: read: connection refused

Probably something trivial but I cannot seem to figure it out. Any ideas?

Seems similar to this one. I added to /etc/hosts and that did the trick.

I too had a similar problem. During the last step the installer tried to ping For unknown reasons the DNS returned only the IPv6 address and for very obscure reasons my debian machine (that lives in VMware) was not able to get a connection.

So I found the IPv4 address and put it in hosts. The installation then arrived to its end but the IPv6 problems are still there.
Thanks for the hint.
