I confirm that the issue is present with the AMI Ubuntu image 20160516.1. I systematically reproduce it by
- launching an instance of the AMI image on EC2 - apt update ; apt install openvpn - configuring the OpenVN server with any configuration (static key for instance https://openvpn.net/index.php/open-source/documentation/miscellaneous/78-static-key-mini-howto.html) - enable OpenVPN at boot - reboot The instance fails to configure its network for the reason described by the OP. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580356 Title: OpenVPN causes reboot failure on Xenial in AWS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvpn/+bug/1580356/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
