Starting with zesty container that has 232-21ubuntu5 installed. Removed libnss-resolve. Reboot. Notice that systemd-resolve is not enabled. Upgrade to 232-21ubuntu6. .... and systemd-resolved was not enabled by default
This is a fail, the version number in postinst is too low when comparing whether or not resolved should be enabled or not. ** Tags removed: verification-needed verification-needed-zesty ** Tags added: verification-failed verification-failed-zesty -- 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/1710410 Title: Must run systemd-resolve --status before DNS resolving is operative Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Zesty: Fix Committed Status in systemd source package in Artful: Fix Released Bug description: [Impact] systemd-resolved is not enabled by default, therefore relies on dbus activation to become active and operatable and update resolvconf with resolved stub resolver [Fix] Enable systemd-resolved in the src:systemd package by default, even when libnss-resolve is not installed [Regression Potential] Minimal, simply the service is now started earlier in the boot, as part of the multi-user.targer, rather than awaiting for dbus activation from command line tool or the nss-resolved module. [Testcase] Debootstrap minimal zesty, without libnss-resolve package installed, boot and check that 127.0.0.53 is present in /etc/resolv.conf and that systemd-resolved.service is running Context: fresh install of zesty via debootstrap --include=nano,dbus,iputils-ping,iproute2 zesty zesty1 http://fr.archive.ubuntu.com/ubuntu ran via asystemd-nspawn with a static IP 1. Upon first connexion, a ping fails: root@zesty1:~# ping google.com ping: google.com: Temporary failure in name resolution 2. The content of /etc/resolv.conf: root@zesty1:~# cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN # 127.0.0.53 is the systemd-resolved stub resolver. # run "systemd-resolve --status" to see details about the actual nameservers. 3.
