I was having the same problem ("If you use one of --cert or --key, you
must use them both" in syslog). Upgrading to 1.8.0-3 fixed the issue for
me.As a minor caveat, simply pointing to the private key file in the UI was not enough and I was getting: nm-openvpn[5972]: OpenSSL: error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch nm-openvpn[5972]: Cannot load private key file /home/tsniatowski/.cert/nm-openvpn/vpn-key.pem Possibly something else needed tweaking, I fixed this by re-importing the .openvpn file I got and then the connection worked. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-openvpn in Ubuntu. https://bugs.launchpad.net/bugs/1754172 Title: NetworkManager breaks OpenVPN configuration on connection Status in network-manager-openvpn package in Ubuntu: Confirmed Bug description: A previously working OpenVPN configuration stopped connecting, with nm-openvpn complaining about wrong options: mar 07 22:35:45 michal-laptop NetworkManager[3172]: <info> [1520458545.8258] audit: op="connection-activate" uuid="e3553582-0f39-404f-bd71-4dc6b92992de" name="Router.Michal" pid=6735 uid=1000 result="success" mar 07 22:35:45 michal-laptop NetworkManager[3172]: <info> [1520458545.8337] vpn-connection[0x55e59e3be750,e3553582-0f39-404f-bd71-4dc6b92992de,"Router.Michal",0]: Started the VPN service, PID 26187 mar 07 22:35:45 michal-laptop NetworkManager[3172]: <info> [1520458545.8421] vpn-connection[0x55e59e3be750,e3553582-0f39-404f-bd71-4dc6b92992de,"Router.Michal",0]: Saw the service appear; activating connection mar 07 22:35:45 michal-laptop NetworkManager[3172]: <info> [1520458545.8611] vpn-connection[0x55e59e3be750,e3553582-0f39-404f-bd71-4dc6b92992de,"Router.Michal",0]: VPN plugin: state changed: starting (3) mar 07 22:35:45 michal-laptop NetworkManager[3172]: <info> [1520458545.8615] vpn-connection[0x55e59e3be750,e3553582-0f39-404f-bd71-4dc6b92992de,"Router.Michal",0]: VPN connection: (ConnectInteractive) reply received mar 07 22:35:45 michal-laptop nm-openvpn[26190]: Options error: If you use one of --cert or --key, you must use them both mar 07 22:35:45 michal-laptop nm-openvpn[26190]: Use --help for more information. mar 07 22:35:45 michal-laptop NetworkManager[3172]: <warn> [1520458545.8648] vpn-connection[0x55e59e3be750,e3553582-0f39-404f-bd71-4dc6b92992de,"Router.Michal",0]: VPN plugin: failed: connect-failed (1) mar 07 22:35:45 michal-laptop NetworkManager[3172]: <warn> [1520458545.8651] vpn-connection[0x55e59e3be750,e3553582-0f39-404f-bd71-4dc6b92992de,"Router.Michal",0]: VPN plugin: failed: connect-failed (1) mar 07 22:35:45 michal-laptop NetworkManager[3172]: <info> [1520458545.8658] vpn-connection[0x55e59e3be750,e3553582-0f39-404f-bd71-4dc6b92992de,"Router.Michal",0]: VPN plugin: state changed: stopping (5) mar 07 22:35:45 michal-laptop NetworkManager[3172]: <info> [1520458545.8660] vpn-connection[0x55e59e3be750,e3553582-0f39-404f-bd71-4dc6b92992de,"Router.Michal",0]: VPN plugin: state changed: stopped (6) mar 07 22:35:45 michal-laptop NetworkManager[3172]: <info> [1520458545.8680] vpn-connection[0x55e59e3be750,e3553582-0f39-404f-bd71-4dc6b92992de,"Router.Michal",0]: VPN service disappeared The config, however, includes correct ca/cert/key stanzas: ca=<redacted>ca.crt cert=<redacted>michal.crt key=<redacted>michal.key The attached screenshot shows a related breakage in the GUI, after making the correct certificate/key file selections, and saving the config, the config file gets broken indeed: ca=<redacted>ca.crt cert=<redacted>ca.crt # no key entry at all ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: network-manager-openvpn 1.8.0-2 ProcVersionSignature: Ubuntu 4.15.0-10.11-generic 4.15.3 Uname: Linux 4.15.0-10-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.8-0ubuntu10 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Wed Mar 7 22:32:57 2018 SourcePackage: network-manager-openvpn UpgradeStatus: Upgraded to bionic on 2018-02-07 (28 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-openvpn/+bug/1754172/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
