@callegar It would be nice to see the full resolvectl status.
Because depending on which things you have configured it might be expected to have DNSSEC validation working, and the request is routed to multiple interfaces, and none of them return results or the results fail to validate. Also note that strict DNSSEC is off by default.... did you turn it on in the first place? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1920781 Title: Mobile phone hotspot unusable due to systemd-resolved not liking the DNS Status in systemd package in Ubuntu: Incomplete Status in systemd source package in Focal: Incomplete Status in systemd source package in Groovy: Incomplete Bug description: Seen in 20.04.
