I've attached the output of `journalctl -u systemd-networkd -u NetworkManager -b`
Just FYI, this is taken from a fresh VM with a basically default Ubuntu Server 24.04 installation after installing ubuntu-desktop-minimal. I had to push some workarounds in our production deployment and I encountered a new/separate bug affecting netplan config so it's just easier to reproduce in a clean VM. The primary issue remains. Running `nmcli device status` gives the below: ebiadmin@test24:~$ nmcli dev status DEVICE TYPE STATE CONNECTION lo loopback connected (externally) lo enp1s0 ethernet unmanaged -- > PS: I guess the expectation here would be for systemd-networkd to keep > managing the network+DNS (which it doesn't for some reason), until reboot or > "netplan apply" is executed. Is that how it worked on 22.04? Yes this is how it worked on 22.04. networkd maintained network+DNS until next reboot as long as "netplan apply" isn't executed. ** Attachment added: "network.journal" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2097769/+attachment/5857420/+files/network.journal -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/2097769 Title: Installation of ubuntu-desktop-minimal breaks DNS Status in netplan.io package in Ubuntu: New Status in systemd package in Ubuntu: Incomplete Bug description: After performing an autoinstall with Ubuntu Server ISO and rebooting, trying to automate the installation of ubuntu-desktop-minimal causes DNS settings to be lost. For our specific use-case, we are installing ubuntu server (fully automated), then using Puppet to install desktop packages. This was working without any manual interaction previously on both Ubuntu 22.04 and 24.04 For the last week or so, deployments of 24.04 (22.04 is still fine) are getting stuck after installing ubuntu-desktop-minimal. The DNS server settings are lost, but IP connectivity remains. Step-by-step 1) Install Ubuntu Server with default network configuration using autoinstall. 2) Reboot and install network-manager (note that everything is still working normally) 3) Install ubuntu-desktop-minimal DNS settings are now lost on the primary interface, yet IP connectivity remains. networkd is still managing the interface, but "netplan get" reports that NetworkManager is the current renderer. ``` network: version: 2 renderer: NetworkManager ethernets: enp1s0: critical: true nameservers: addresses: - 172.16.1.100 - 172.18.1.100 dhcp-identifier: "mac" dhcp4: true ``` We can workaround the problem forcing an extra reboot after installing ubuntu-desktop-minimal. But previously this workflow was fine without rebooting until the very end of the config.
