Public bug reported: NetworkManager as of 1.10.6-2ubuntu1.2 has cause a regression whereby a VPN connection which sets it's dns-priority to a negative value, which should cause the DNS server supplied by the DNS connection to be placed first, instead now refuses to place the DNS server into the resolver under any circumstance.
Pinning the 1.10.6-2ubuntu1.1 works around the issue. I suspect the fix-dns-leak-lp1754671.patch has caused this regression. This patch should be reverted as soon as possible to restore proper functionality of network manager with respect to VPN servers with DNS resolvers. $ lsb_release -rd Description: Ubuntu 18.04.3 LTS Release: 18.04 ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- 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/1851407 Title: NetworkManager 1.10.6-2ubuntu1.2 breaks VPN DNS Status in network-manager package in Ubuntu: New Bug description: NetworkManager as of 1.10.6-2ubuntu1.2 has cause a regression whereby a VPN connection which sets it's dns-priority to a negative value, which should cause the DNS server supplied by the DNS connection to be placed first, instead now refuses to place the DNS server into the resolver under any circumstance.
