@toto-23, you may want to try putting the following in /etc/systemd/resolved.conf as a temporary workaround:
[Resolve] Domains= Note that there is nothing after the equals sign. According to the docs it will override anything systemd-resolved reads from /etc/resolv.conf with an empty list. This is the workaround that works for me on 17.04, so maybe it also works on 17.10. On my 17.10 test VM it at least doesn't seem to cause any problems. Interestingly, per-connection search paths still work for me (the documentation is ambiguous about whether Domains= overrides them or not) on both 17.04 and 17.10. So setting "Domains=" by default might be enough to fix the bug? Not sure whether that has unintended side effects, though. -- 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/1714803 Title: Search list in resolv.conf breaks resolving for that domain Status in systemd package in Ubuntu: Incomplete Bug description: Ubuntu 17.04 systemd 232-21ubuntu5 Adding a domain to the search list in /etc/resolv.conf breaks resolving for that domain. Not only does the search list not get used as expected, but host names in the domain cannot be resolved by systemd-resolved at all. I just ran into this after upgrading from ubuntu 16.04 to 17.04 which enabled systemd-resolved. I have for a long time used resolveconf to add a 'search my-domain'-line to my /etc/resolv.conf. Example of expected behaviour. With Googles DNS server (8.8.8.8) and ubuntu.com in the search list in /etc/resolv.conf. Both dig and systemd-resolve can resolve www.ubuntu.com and www: $ cat /etc/resolv.conf nameserver 8.8.8.8 search ubuntu.com $ dig +nostat +nocmd www.ubuntu.com ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 55037 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ;; QUESTION SECTION: ;www.ubuntu.com.
