[Bug 1882162] Re: subiquity creates wrong network configuration (wrong NIC name)

[Don Williams]

I wanted to add to this as well I downloaded this build as well and I
can see my DHCP offer the IP address but the Ubunutu server does not ACK
the offer or even see it from tcpdump. This is also on unRAID as well
using VirtIO network adapter.

Title:
  subiquity creates wrong network configuration (wrong NIC name)

Status in subiquity package in Ubuntu:
  Confirmed

Bug description:
  I already reported a bug against other tool but I think it should be
  filled against subiquity.

  https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1881832

  Ubuntu server 20.04 and 18.04.4. When I installed them on virtual
  machine (FreeNAS 11.3, VMware ESXi 6.7), installation was OK but after
  reboot, virtual machine had no network connectivity, IP address from
  DHCP server was not requested. NIC interface was enp0s4. I can ask for
  IP address manualy with "sudo dhclient enp0s4" and it works!

  I think that issue is that subiquity creates wrong network
  configuration, this is file after install. Nnote, that enp0s5 is
  configured with DHCP4, but real NIC is enp0s4...

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

  #####
  # This is the network config written by 'subiquity'
  network:
    ethernets:
      enp0s5:
        dhcp4: true
    version: 2

  I fixed this issue by replacing "enp0s5" with "enp0s4" in file
  /etc/netplan/00-installer-config.yaml. Rebooted machine asked for IP
  address from DHCP server and I like it...
