You have been subscribed to a public bug: 1) on a »Ubuntu 16.04.4 LTS« with static ip configuration in /etc/network/interfaces and manual entries in /etc/resolv.conf 2) network-manager 1.2.6-0ubuntu0.16.04.2 is enabled but doesn’t manage any interfaces and therefore doesn’t start dnsmasq
3) using hostnamectl and updating /etc/hosts doesn’t break dns resolution 4) changing the hostname however triggers NetworkManager to start dnsmasq and overwrite /etc/resolv.conf Workarounds are chattr’ing /etc/resolv.conf or – in this case – disabling NetworkManager but i think this shouldn’t happen. cat /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile,ofono dns=dnsmasq [ifupdown] managed=false ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New ** Tags: xenial -- hostname change with static ip overwrites (manual) resolv.conf https://bugs.launchpad.net/bugs/1761986 You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. -- 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
