[Bug 2024546] Re: Netplan not bringing up IPv6 address when dhcp6: true specified

[Lukas Märdian]

This seems to be a more generic issue with DHCP client vs Oracle OCI and
unrelated to Netplan:

Title:
  DHCP not bringing up IPv6 address when dhcp6: true specified

Status in netplan:
  Invalid
Status in isc-dhcp package in Ubuntu:
  New

Bug description:
  I have a netplan configuration with dhcp6: true specified for my
  network interface, however no IPv6 address comes up.

  dhclient -6 brings the address up without issue, proving that the DHCP
  server is responding.

  So why isn't Netplan configuring the IP address?

  network:
      version: 2
      ethernets:
          enp0s6:
              dhcp4: true
              dhcp6: true
              match:
                  macaddress: 02:00:17:xx:xx:xx
              set-name: enp0s6
