unshare -c -r --keep-caps
Oops, I meant "unshare -n -r --keep-caps".
$ python3 -c 'from socket import *; getaddrinfo("127.0.0.1", port=1, flags=AI_ADDRCONFIG)'
Note that the above does not fail when only loopback is configured, so it seems to be something else than #952740.
I haven't figured out what's exactly going on in #1004461, because the package FTBFS for me in a different way that I don't understand. :-/
