Server 22.04.1 subiquity autoinstall - system-install command fails after changing NIC name using netplan

Issue:

I'm trying to use packer to create an Ubuntu Server 22.04 image and I'm running into issues when it comes to renaming the NIC using a valid netplan config and then also installing one package.

A couple things to note on the background:

I'm renaming the NIC because I'm trying to use terraform to set the NIC config on startup using proxmox with cloud-init. When cloud-init runs on the cloned image it seems to want to rename the NIC on first boot and since it cannot rename the NIC (to eth0 from ens18) on the fly it takes a second reboot before cloud-init sets the proper IP address on the VM. This is less than ideal when I want to be able to spin an ubuntu server up with terraform since it takes a manual reboot.

I've had no issues with Proxmox and cloud-init drive/config settings it provides for the following OS's:

AlmaLinux 8 & 9

RHEL 7, 8, & 9

Windows Server 2012, 2016, 2019, and 2022 (Cloudbase-init)

They all just seem to accept the cloud-init config that terraform sends over to proxmox to use and all is good to go. All this to say that maybe proxmox shouldn't be renaming the NIC, but Ubuntu Server is the first OS I've had issues with this on and I'm not really looking for a solution anywhere besides Ubuntu currently.

I need to install qemu-guest-agent on the VM so that packer is able to read in the IP address from the Proxmox API so it knows who to connect to.

Specifics:

I can install qemu-guest-agent if I don't specify any network settings and let subiquity/netplan provide the defaults. When I do this, the final autoinstall-user-data located in /var/log/installer on a successful autoinstall shows the following network and packages config:

autoinstall:

<snipped>

  network:

    ethernets:

      ens18:

        dhcp4: true

    version: 2

  packages:

  - qemu-guest-agent

<snipped>

I can successfully rename the NIC using subiquity/netplan. When this is done, it fails to install qemu-guest-agent and fails the build process. Here's the config I use for that:

  network:

    ethernets:

      ens18:

        match:

          driver: e1000

        dhcp4: true

        set-name: eth0

    version: 2

  packages:

  - qemu-guest-agent

The above network: block does successfully rename the NIC to eth0 AND I have full networking on the broken install. I'm able to ping something such as google.com and am also able to SSH into the machine. I can see from the logs that the rename is successful and I can verify the new NIC name on the failed install when it pops me into a shell.

Below are the errors this then runs into after the NIC rename.

At this point I'm not too sure why it states it's not able to locate the package after the NIC is renamed. I'm a bit stumped at this point because the VM does have full internet access after I'm presented the shell.

Any sort of help/troubleshooting steps are appreciated. Happy to provide any info I can.

I like to configure networking using late-commands.

#cloud-config

autoinstall:

  late-commands:

    - |

      rm /target/etc/netplan/00-installer-config.yaml

      cat <<EOF > /target/etc/netplan/80-my.yaml

      network:

        ethernets:

          ens18:

            match:

              driver: e1000

            dhcp4: true

            set-name: eth0

        version: 2

      EOF

how it works

If there is no network configuration block in your user-data file then the installer (subiquity) will use a generic netplan config. Later, subiquity will generate a netplan config for the installed system and will also use it for the installer environment. In late-commands you can delete the subiquity generated config and replace it with whatever you want. This will only affect the installed system.
