[Bug 1751151] Re: Installing via IPv6 results in invalid netplan yaml

[Thomas]

ok, I also could add the quotes and now netplan accept the file:

root at bk1:~# cat /etc/netplan/01-netcfg.yaml
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    ens18:
      dhcp4: false
      dhcp6: false
      accept-ra: false
      addresses: [ "2a01:4f8:XX:XXXX::XX/64" ]
      gateway6: "2a01:4f8:XX:XXXX::X"
      nameservers:
        addresses: ["2a01:4f8:0:1::add:1010", "2a01:4f8:0:1::add:9999", "2a01:4f8:0:1::add:9898"]

Title:
  Installing via IPv6 results in invalid netplan yaml

Status in netcfg package in Ubuntu:
  Fix Released
Status in nplan package in Ubuntu:
  Confirmed

Bug description:
  I installed ubuntu 17.10 using the mini iso. The network is IPv6 only, so I used that (successfully) to do a network install of ubuntu 17.10. However, the resulting system
  was unreachable over the network. The installer generated 01-netcfg.yaml looked like:

  ```
  # This file describes the network interfaces available on your system
  # For more information, see netplan(5).
  network:
    version: 2
    renderer: networkd
    ethernets:
      enp24s0f0:
        addresses: [ XXXX:XXX:X:XX::XX:XX/112 ]
        gateway6: XXXX:XXX:X:XX::XX:X
        nameservers:
            search: [ XXXXXXXXX.XX ]
            addresses:
                - XXXX:XXX:X:X::X
  ```

  However,

  `netplan apply` complains:

  `Invalid YAML at //etc/netplan/01-netcfg.yaml line 7 column 23: found
  unexpected ':'`

  This is remedied, by putting the ipv6 address into quotes, i.e.:
  ```
  addresses: [ "XXXX:XXX:X:XX::XX:XX/112" ]
  ```
