Hello, there seems to be a patch available to fix this bug:
https://github.com/canonical/cloud-init/commit/f75be2ebe15b0dc78092fe47b1ef8d506607e9daThe earliest official release of cloud-init that includes this fix is cloud-init version 23.1
To test this you can use this comand to simulate the config generation:cloud-init devel net-convert -D debian -p /path/to/network-config.yaml -k yaml -d /some/outputdir/ -O networkd
With the config from #10 (after adding a missing "'" to the ipv6 gateway address) this would result in this working systemd .network file:
[Address] Address=192.0.2.60/24 [Address] Address=2001:db8:aaa:bbb::ccc/64 [Match] MACAddress=ff:ff:ff:ff:ff:ff Name=eth0 [Network] DHCP=no DNS=127.0.0.1 [Route] Gateway=192.0.2.62 [Route] Gateway=2001:db8:aaa:bbb::ddd Would it be possible to backport this to stable?
