The premis is that you have a network device with a "link local" (aka: "scopeid 0x20<link>") inet6 address.
In my case, "ifconfig enp4s0" shows a line like this: inet6 fe80::4687:fcff:fe9e:4ac7 prefixlen 64 scopeid 0x20<link> If your machine does NOT have such a line, then I must admit, I don't know how to produce one. Mine had it from default setup. If your machine DOES have an inet6 link local address, then (in a shell) run "host $(hostname)" and it is likely to return an inet (ipv4) address (that's just fine) AND the link local inet6 address. If your "host $(hostname)" doesn't give you any inet6 address, or gives you one with %network-name appended, then you might have a different version of "systemd" than 237-3ubuntu10.33 (as included in 18.04) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853669 Title: systemd resolves own hostname to link local ipv6 address To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1853669/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
