Is there a 16.04 package? This was a regression there caused by an earlier update.
I have users reporting the same bizarre behaviour I wasn't able to clearly describe before — essentially, DNS being sent out seemingly random interfaces (sometimes VPN, sometimes local). My advice to just install this package *and* manually set dns-priority=-1,dns-search=~. and get on with life even though you really shouldn't have to manually set the latter, doesn't work for the 16.04 users... And yes, when other things stop being on fire I need to undo those settings and try to work out what's going wrong. We aren't using systemd-resolve here because historically it also hasn't worked right while dnsmasq did. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1754671 Title: Full-tunnel VPN DNS leakage regression Status in NetworkManager: Fix Released Status in network-manager package in Ubuntu: Fix Released Status in network-manager source package in Bionic: Fix Committed Bug description: * Impact When using a VPN the DNS requests might still be sent to a DNS server outside the VPN when they should not * Test case Configure the system to send all the traffic to a VPN, do a name resolution, the request should not go to the public DNS server (to be checked by capturing the traffic by example with wireshark) * Regression potential The code change the handling of DNS servers when using a VPN, we should check that name resolution still work whne using a VPN in different configurations ----------------- In 16.04 the NetworkManager package used to carry this patch: http://bazaar.launchpad.net/~network-manager/network-manager/ubuntu/view/head:/debian/patches/Filter-DNS-servers-to-add-to-dnsmasq-based-on-availa.patch It fixed the DNS setup so that when I'm on the VPN, I am not sending unencrypted DNS queries to the (potentially hostile) local nameservers. This patch disappeared in an update. I think it was present in 1.2.2-0ubuntu0.16.04.4 but was dropped some time later. This security bug exists upstream too: https://bugzilla.gnome.org/show_bug.cgi?id=746422 It's not a *regression* there though, as they didn't fix it yet (unfortunately!)
