Package: systemd-resolved Version: 257.3-1 Hello,
On trixie, during the startup of systemd-resolved I observe the info message: "Defaulting to hostname 'linux'." /etc/hostname is populated and the correct hostname is returned by hostnamectl and hostname Attempting to set the hostname (with either hostnamectl or hostname) results in systemd-resolved emitting the warning message: "Failed to determine the local hostname and LLMNR/mDNS names, ignoring: Invalid argument" I prefer to set ReadEtcHosts=no, but observe the behaviour above with ReadEtcHosts set to either yes or no. However, without suitable entries for the local hostname in /etc/hosts, or if ReadEtcHosts=no, systemd-resolved does not synthesize records for the local hostname, and so queries for the local hostname are not found, oddly (to me at least!) causing sudo to emit a warning upon use that it is unable to resolve the host. I do not observe the same behaviour on any of my bookworm machines using systemd-resolved. Thank you, Phil
