ACK. IIRC there's a "nm-generated" flag inside the NM connection profile, which we could check to avoid calling into the libnetplan integration if exists.
So this actually affects NetworkManager's libnetplan integration patch more than Netplan itself, IMO: https://github.com/slyon/NetworkManager/tree/slyon/backend-1.36.6 ** Changed in: netplan Status: New => Triaged ** Changed in: netplan Importance: Undecided => Medium ** Changed in: netplan Importance: Medium => High ** Also affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1998207 Title: netplan network-manager plugin tries to save temporary connections Status in netplan: Triaged Status in network-manager package in Ubuntu: New Bug description: When creating an OpenVPN connection, a temporal connection called tunN is created. For instance, after activating a connection called vpntest, I have: NAME UUID TYPE DEVICE vpntest 458856e6-8f0f-4dc6-82f2-dd72868252a0 vpn ens3 tun0 1eb1dbe8-5678-4818-9adf-fb2dc01ed132 tun tun0 tun0 is created/removed after activating/deactivating vpntest and should not really be saved, but I see netplan adding it in /etc/netplan. And while doing so the plugin also reports some errors (I see these when stopping the connection): Nov 28 16:16:57 ubuntu NetworkManager: <error> [1669652217.2920] BUG: the profile cannot be stored in keyfile format without becoming unusable: cannot access file: No such file or directory Nov 28 16:16:57 ubuntu NetworkManager: ((src/libnm-core-impl/nm-connection.c:342)): assertion '<dropped>' failed Nov 28 16:16:57 ubuntu NetworkManager: <warn> [1669652217.2920] keyfile: commit: failure to write 1eb1dbe8-5678-4818-9adf-fb2dc01ed132 ((null)) to "/run/NetworkManager/system-connections/tun0-1eb1dbe8-5678-4818-9adf-fb2dc01ed132.nmconnection": keyfile writer produces an invalid connection: cannot access file: No such file or directory To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/1998207/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : email@example.com Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
