After upgrading several 22.04 servers to 24.04, the NetworkManager connection files were automatically migrated to netplan, and new connections automatically go to /etc/netplan.
Some of the issues I've seen: 1) Forced UUID based file names: Previously, I would edit /etc/NetworkMananger/system-connections/vlan31.nmconnection. Now I need to edit /etc/netplan/90-NM-37a0bb34-7f68-32a0-0002-000000000031.yaml. I can't have normal file names anymore; I need to grep through all my connections to locate it, and then copy/paste the resulting filename. 2) If I manually rename /etc/netplan/90-NM-37a0bb34-7f68-32a0-0002-000000000031.yaml to /etc/netplan/90-vlan31.yaml and reboot, and then use nmtui or the GUI to edit the connection, I get yet another 90-NM-37a0bb34-7f68-32a0-0002-000000000031.yaml file. Now I have two files. 3) Confusing contents. For example, that VLAN connection contains: network: version: 2 vlans: enp1s0.31: renderer: NetworkManager addresses: - "1.2.3.4/29" ... networkmanager: uuid: "37a0bb34-7f68-32a0-0002-000000000031" name: "VLAN31" passthrough: connection.timestamp: "1726302619" ethernet._: "" vlan.flags: "1" ipv4.address1: "1.2.3.4/29,1.2.3.1" So for example, if I need to change the IP, I need to change it twice, once under "addresses" and once under "passthrough". 4) Badly mapped content. In the example above, I have: vlans: enp1s0.31: While in Network Manager I didn't need to specify the interface name. If I replaced my network card e.g. from enp1s0 to enp2s0, the VLAN would automatically be named enp2s0.31. Now if I delete the VLAN interface name from the NetworkManager text box and save the connection, it's not deleted like it should. These are from the first days of use, I'm sure there will be more issues if we keep using this backend. Please do add a configuration option to avoid the yaml NM backend. The compilation time option isn't appropriate, we shouldn't be risking to lose all security updates because of local compilation of packages. Thank you! (and if someone creates a PPA with an un-patched network manager to be able to function until this issue is properly resolved, please notify us in this topic :)) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/2041491 Title: Provide an option to avoid the yaml NM backend Status in netplan.io package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: Hi, recently netplan added support for a yaml NM backend: https://discourse.ubuntu.com/t/call-for-testing-networkmanager-yaml- settings/32420 The rationale is that "the descriptive YAML layer is especially useful in cloud environments": https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/556 It's great that you care about that user group! Please also care for the rest of us that do not use cloud environments! For example, I routinely review, clone, backup or even directly edit the /etc/NetworkManager/system-connections files in my desktops and servers, in all distributions. Having an Ubuntu-specific way to do things will make things harder for me. I will have to learn a new Ubuntu-specific syntax, develop scripts and methods to convert my connections between distributions, I will need to discover and report bugs in the netplan <=> nm mapping etc... I.e. Ubuntu is great for the cloud, and it's awesome that you want to provide a unified yaml-based experience for cloud-init etc. But Ubuntu is also great outside the cloud; please allow us to continue having a unified experience between distributions (i.e. directly using nm or systemd-networkd) without enforcing an Ubuntu-specific way of doing things (netplan) to us. For Ubuntu 24.04+, please provide an option to avoid the yaml NM backend, thank you very much!
