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!
