Public bug reported: Hi,
Using manual provider on top of VMWare. Juju: 2.9.14 VM: Focal Containers: Bionic I've noticed that, in a given Focal host, 2x Bionic containers may have different behavior: one successfully completes cloud-init whereas the other fails. The failed container errors at "apt update" in cloud-init with: Err:1 http://archive.ubuntu.com/ubuntu bionic InRelease Something wicked happened resolving 'PROXY_IP:<PORT>' (-9 - Address family for hostname not supported) (Likely this is the line where it breaks: https://github.com/Debian/apt/blob/766b24b7f7484751950c76bc66d3d6cdeaf949a5/methods/connect.cc#L436) Failed container, full cloud-init-output.log: https://pastebin.canonical.com/p/hKNw49mvJP/ Successful container, full cloud-init-output.log: https://pastebin.canonical.com/p/P6MZdQPrWd/ Host syslog: https://pastebin.canonical.com/p/jjMmWRFd9y/ I can see that, on the host, dnsmasq served the FAN IP to the broken container after the "apt-update" was called. ----- FAILED CONTAINER -----: Sep 19 13:02:14 lma-stack-2 dnsmasq-dhcp[1243]: DHCPOFFER(fan-252) 252.252.15.198 00:16:3e:da:dd:c4 apt-update on cloud-init was ran: Cloud-init v. 21.2-3-g899bfaa9-0ubuntu2~18.04.1 running 'modules:config' at Sun, 19 Sep 2021 13:02:13 +0000.
