Hi, cloud-init has never updated resolv.conf directly. /etc/resolv.conf in 16.04 is managed via resolvconf through /etc/network/interfaces. /etc/resolv.conf in 18.04 is managed via systemd-resolve (netplan -> systemd-networkd -> systemd-resolve).
Can you provide the content of: systemd-resolve --status --no-pager And does this happen in the ephemeral environment, the installed environment, or both? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1750884 Title: [2.4, bionic] /etc/resolv.conf not configured correctly in Bionic, leads to no DNS resolution To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1750884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
