Can you confirm you are seeing the "udp_xmit failed ... with err=-1:No such device" error ?
If you are, this is not a network-manager-l2tp bug, but a kernel 4.15 bug, I posted a xl2tpd bug report and workaround patch for Ubuntu 18.04's xl2tpd package almost a month before Bionic Beaver was released : https://bugs.launchpad.net/ubuntu/+source/xl2tpd/+bug/1760796 The bug is receiving very little user attention, only 7 people have voted for it, ho[pefully the more people vote for it the sooner it will receive attention and someone will apply the patch. xl2tpd 1.3.12 hasn't been released yet, can you confirm you built from the xl2tpd 1.3.12 git branch? i.e. : git clone -b 1.3.12 https://github.com/xelerance/xl2tpd.git cd xl2tpd make sudo cp xl2tpd /usr/sbin/xl2tpd xl2tpd 1.3.12 git branch definitely fixed the issue for me on Ubuntu 18.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771223 Title: Cannot connect to L2TP network To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-l2tp/+bug/1771223/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
