I had troubles with DNS resolution in last days after reboot and I think it may be related to resolvconf package update. I spotted following entries in resolvconf-pull-resolved.service journal:
mar 14 09:30:01 *** systemd[1]: resolvconf-pull-resolved.service: Start request repeated too quickly. mar 14 09:30:01 *** systemd[1]: resolvconf-pull-resolved.service: Failed with result 'start-limit-hit'. mar 14 09:30:01 *** systemd[1]: Failed to start resolvconf-pull-resolved.service. Because of that DNS resolution was not working after boot but I used workaround of disabling and enabling Wifi from GUI. I guess resolvconf-pull-resolved.service was started too many times right after booting the system. For now I just uninstalled resolvconf package and it should fix it but I hope my message can help to track the problem. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to resolvconf in Ubuntu. https://bugs.launchpad.net/bugs/1819625 Title: Package resolvconf=1.79ubuntu10.18.04.1 broken Status in resolvconf package in Ubuntu: Confirmed Status in resolvconf source package in Bionic: Fix Committed Status in resolvconf source package in Cosmic: Fix Released Bug description: The package resolveconf version 1.79ubuntu10.18.04.1 is broken.
