You seem to have a bad /etc/init.d/netplan file on the system; it's not coming from the netplan.io package. You should make sure you do not have the 'netplan' package installed (the network plan server).
Please attach the contents of /etc/NetworkManager/NetworkManager.conf. ** Package changed: netplan.io (Ubuntu) => network-manager (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1771971 Title: dns broken after upgrade to bionic Status in network-manager package in Ubuntu: Incomplete Bug description: After upgrade to Bionic my DNS is broken. `resolv.conf` contains ``` # 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. nameserver 127.0.0.53 ``` and network is configured via network manager and DHCP. But DNS will only work when entering the IP manually. Maybe something wrong with netplan? ``` ~$ systemd-resolve --status Global 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 3 (wlan0) Current Scopes: none LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no Link 2 (eth0) Current Scopes: none LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no ``` ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: netplan.io 0.36.1 ProcVersionSignature: Ubuntu 4.15.0-20.21-lowlatency 4.15.17 Uname: Linux 4.15.0-20-lowlatency x86_64 ApportVersion: 2.20.9-0ubuntu7 Architecture: amd64 CurrentDesktop: i3 Date: Fri May 18 09:56:49 2018 EcryptfsInUse: Yes InstallationDate: Installed on 2014-06-03 (1444 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) SourcePackage: netplan.io UpgradeStatus: Upgraded to bionic on 2018-05-13 (5 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1771971/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
