Michael Gale, your issue is different to the OP's one. The routes the OP has entered are all CIDR notable, he even uses CIDR when entering them via command line.
So please report a new bug, showing which routes you have entered and how they end up in /etc/NetworkManager/system-connections. In addition, you could report a bug upstream, suggesting to let the rutes be saved in /etc/NetworkManager/system-connections in dotted-quad notation if they cannot be represented in CIDR notation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1608646 Title: ip4 static routes added in NetworkManager UI fail and prevent connection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1608646/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
