It's interesting that for both of you the output of "resolvctl" shows "resolv.conf mode: foreign", which is non-default and unsupported by Ubuntu. It should be using "stub" mode.
/etc/resolv.conf should be a symlink to /run/systemd/resolve/stub- resolv.conf in order to be managed by sd-resolved. But it seems to be managed by a different tool on your system. Can you please revert to the default, e.g. using: $ ls -la /etc/resolv.conf $ mv /etc/resolv.conf /etc/resolv.conf.BAK $ ln -s /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf $ systemctl restart systemd-resolved $ resolvectl And report back if this improves the situation for you? ** Changed in: netplan.io (Ubuntu) Status: Incomplete => Invalid ** Changed in: systemd (Ubuntu) Status: Confirmed => Incomplete -- 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/1982553 Title: Search domains not working after upgrading to Ubuntu 22.04 Status in netplan.io package in Ubuntu: Invalid Status in systemd package in Ubuntu: Incomplete Bug description: Hello, After upgrading to Ubuntu 22.04, I noticed that search domains are not working anymore. Either I configure search domains via netplan or with graphical "nm- connection-editor", this is not taken into account when resolving domain names. For instance if I configure "domain.com" in search domains list, looking for "host" does not look for "host.domain.com". This is confirmed with a wireshark capture. Consequently if I want to connect with SSH to host.domain.com, I have to type the entire url. In Ubuntu 20.04 this works correctly. With a packet capture I can see one domain lookup for each of my search domains configured.
