Title: xenial2bionic release upgrade loses DNS: empty resolv.conf Status in resolvconf package in Ubuntu: Fix Released Bug description: Note: I'm not sure which package better represents this bug, so I used systemd, because /etc/resolv.conf had no "nameserver 127.0.0.53" entry after the upgrade. I did a plain standard lxd deploy of xenial, using the default images. Upgraded it to the latest xenial packages, and then issued a release upgrade to bionic. At the end of the upgrade process, rebooted, and when the system came back up, /etc/resolv.conf had no nameserver entries: root@xenial2bionic:~# 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. That was its whole content. Before the upgrade, in xenial, it had: root@xenial2bionic:~# 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 nameserver 10.0.100.1 search lxd systemd-resolve in the system after the upgrade to bionic was working just fine: root@xenial2bionic:~# systemd-resolve --status Global DNS Servers: 10.0.100.1 DNS Domain: lxd DNSSEC NTA: 10.in-addr.arpa 16.172.in-addr.arpa 168.192.in-addr.arpa 17.172.in-addr.arpa 18.172.in-addr.arpa 19.172.in-addr.arpa 20.172.in-addr.arpa 21.172.in-addr.arpa 22.172.in-addr.arpa 23.172.in-addr.arpa 24.172.in-addr.arpa 25.172.in-addr.arpa 26.172.in-addr.arpa 27.172.in-addr.arpa 28.172.in-addr.arpa 29.172.in-addr.arpa 30.172.in-addr.arpa 31.172.in-addr.arpa corp d.f.ip6.arpa home internal intranet lan local private test Link 34 (eth0) Current Scopes: none LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: systemd 237-3ubuntu7 ProcVersionSignature: Ubuntu 4.15.0-13.14-generic 4.15.10 Uname: Linux 4.15.0-13-generic x86_64 ApportVersion: 2.20.9-0ubuntu4 Architecture: amd64 Date: Wed Apr 11 17:31:08 2018 MachineType: LENOVO 20HRCTO1WW ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-13-generic.efi.signed root=ZFS=nsnx/ROOT/ubuntu ro quiet splash vt.handoff=1 SourcePackage: systemd UpgradeStatus: Upgraded to bionic on 2018-04-11 (0 days ago) dmi.bios.date: 11/09/2017 dmi.bios.vendor: LENOVO dmi.bios.version: N1MET41W (1.26 ) dmi.board.asset.tag: Not Available dmi.board.name: 20HRCTO1WW dmi.board.vendor: LENOVO dmi.board.version: SDK0J40709 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN1MET41W(1.26):bd11/09/2017:svnLENOVO:pn20HRCTO1WW:pvrThinkPadX1Carbon5th:rvnLENOVO:rn20HRCTO1WW:rvrSDK0J40709WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad X1 Carbon 5th dmi.product.name: 20HRCTO1WW dmi.product.version: ThinkPad X1 Carbon 5th dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/1763108/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
