[Bug 1826459] Re: systemd-networkd not installing GatewayOnlink=true

enp0s31f6: Could not set route: Invalid argument
enp0s31f6: Routes set

      addresses:
      - 95.216.96.148/26
      gateway4: 95.216.96.129
      routes:
      - on-link: true
        to: 95.216.96.148/26
        via: 95.216.96.129

I do not quite understand what above is supposed to mean.

95.216.96.128/26 dev enp0s31f6 proto kernel scope link src 95.216.96.148
is a normal routing that is added for the self owned ip addresses, such
that one shouldn't need to go via anything to talk to oneself.

Is that a valid route?

Also I see messages that link is not managed by us, and then later
magically has an up to date state.

I don't quite understand how above is expected to work, nor what is or
isn't broken in networkd. I'll need to seek further help from netplan
developers.
