Package: apt-cacher-ng Version: 3.6.4-1 Severity: normal Tags: ipv6 Dear maintainer,
I have a stock apt-cacher-ng on my laptop. Apt's Acquire::HTTP::Proxy is set to "http://[::1]:3142";. I have an ordinary apt source configured for <http://silentflame.com/debian>. In my /etc/hosts I have a line like this: fdff:9895:c0d0:1::3 silentflame.com www.silentflame.com [...] That IPv6 address is the VPN address of the web server serving silentflame.com. The VPN is IPv6-only. So, it is possible to reach the web server via IPv6 on the VPN, or via IPv4 or IPv6 via the public Internet. What I expect to happen is that apt-cacher-ng obtains files from silentflame.com via the VPN, using IPv6. However, this works only if my primary network interface, wlp0s20f3, has an IPv6 address. When wlp0s20f3 has only an IPv4 address, I get errors like this: spwhitton@melete:~>sudo apt-get update Err:1 http://silentflame.com/debian bullseye InRelease 503 DNS error - system error [IP: ::1 3142] 'curl http://silentflame.com/debian/dists/bullseye/InRelease' can successfully retrieve files over HTTP over the VPN, regardless of what addresses wlp0s20f3 has, as you would expect. A work around is to add a public Internet IPv4 entry for silentflame.com to /etc/hosts: 188.34.164.90 silentflame.com But that shouldn't be necessary, right?
