I have a very similar problem when using a PPTP VPN. I also have Ubuntu 18.04.1 LTS with the following packages installed:
network-manager 1.10.6-2ubuntu1.1 network-manager-config-connectivity-ubuntu 1.10.6-2ubuntu1.1 network-manager-gnome 1.8.10-2ubuntu1 network-manager-pptp 1.2.6-1 network-manager-pptp-gnome 1.2.6-1 systemd 237-3ubuntu10.9 Before connecting to the VPN I see the following permissions in the /run/systemd/resolve directory: $ ls -l /run/systemd/resolve/ razem 12 drwx------ 2 systemd-resolve systemd-resolve 60 gru 13 23:03 netif -rw-r--r-- 1 systemd-resolve systemd-resolve 609 gru 13 23:03 resolv.conf -rw-r--r-- 1 systemd-resolve systemd-resolve 719 gru 13 23:03 stub-resolv.conf -rw-r--r-- 1 root root 747 gru 13 22:58 stub-resolv.conf.tmp I do not see any changes in permissions after connecting to the PPTP VPN. However after disconnecting the VPN the permissions change as in the original bug report: $ ls -l /run/systemd/resolve/ razem 12 drwx------ 2 systemd-resolve systemd-resolve 60 gru 13 23:23 netif -rw-r--r-- 1 systemd-resolve systemd-resolve 681 gru 13 23:23 resolv.conf -rw------- 1 root root 719 gru 13 23:03 stub-resolv.conf -rw-r--r-- 1 root root 747 gru 13 23:23 stub-resolv.conf.tmp With such permissions the DNS resolution process is broken. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1793427 Title: network-manager-fortisslvpn breaks mode of /run/systemd/resolv/stub- resolv.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-fortisslvpn/+bug/1793427/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
