Title:
  "ip address show" does not show all IP addresses of a network
  interface

Status in netplan.io package in Ubuntu:
  Expired

Bug description:
  Using ubuntu 22.04 I try to assign the two IP addresses
  `192.168.200.100` and `169.254.1.0` to the ethernet device
  `enx00e04c680202`. Following [this tutorial][1] and [this answer][2] I
  created a file `/etc/netplan/01-network-config_home.yaml` with the
  following content:

      network:
        version: 2
        renderer: NetworkManager
        ethernets:
          enx00e04c680202:
            addresses:
              - 192.168.200.100/24
              - 169.254.1.100/24
            routes:
             - to: default
               via: 192.168.200.220
               metric: 200
            routes:
             - to: default
               via: 169.254.1.220
               metric: 300

  
  and applied the changes using the command

      sudo netplan apply

  
  I checked the configuration with the command `ip address show dev enx00e04c680202`, but it seems only one address is shown:

      3: enx00e04c680202: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
          link/ether 00:e0:4c:68:02:02 brd ff:ff:ff:ff:ff:ff
          inet 192.168.200.100/24 brd 192.168.200.255 scope global noprefixroute enx00e04c680202
             valid_lft forever preferred_lft forever

  But the other configured address `169.254.1.0` seems to be working; I
  am able to connect to a device with the IP address 169.254.1.0.


  However, when I add an IP address to that adapter `enx00e04c680202`
  using the following command

      sudo ip addr add 169.254.1.100/24 dev enx00e04c680202

  then I see the following output of the command `ip address show dev
  enx00e04c680202`:

      3: enx00e04c680202: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
          link/ether 00:e0:4c:68:02:02 brd ff:ff:ff:ff:ff:ff
          inet 192.168.200.100/24 brd 192.168.200.255 scope global noprefixroute enx00e04c680202
             valid_lft forever preferred_lft forever
          inet 169.254.1.100/24 scope global enx00e04c680202
             valid_lft forever preferred_lft forever

  This is what I would expect in both cases.

  It has been suggested that this is a bug.
