error: NetlinkListenerWithCache.addr_add_dry_run() got an unexpected keyword argument 'nodad'

[junepark678]

Dry run fails due to this error

specifically, I think the error is at https://github.com/CumulusNetworks/ifupdown2/blob/master/ifupdown2/lib/nlcache.py#L3146

Culprit config file:

auto sit0
iface sit0 inet6 tunnel
        mode sit
        address <IPv6 IP address> 
        endpoint <IPv4 address of SIT endpoint> 
        local <IPv4 address of local computer>
        ttl 255
        gateway <IPv6 Gateway>

this also happens with

iface vmbr0 inet6 static
        address fd00:6969::1/64

I've got the same problem after changing my /etc/network/interfaces. In my case: ifup --no-act enp193s0f0np0 got the output:

error: NetlinkListenerWithCache.addr_add_dry_run() got an unexpected keyword argument 'nodad'
error: NetlinkListenerWithCache.addr_add_dry_run() got an unexpected keyword argument 'nodad'

Thanks to ChatGPT, I've tried the tool ifreload, and first did a ifreload --syntax-check --all which returned without error, and then did a ifreload --all which also returned without error. Finally I did a ifup --no-act enp193s0f0np0 again and this time, it returned without error.

According to ChatGPT a ifreload --all might have reloaded the cache or some internal state of ifupdown2 somehow, so that's why the error: NetlinkListenerWithCache.addr_add_dry_run() got an unexpected keyword argument 'nodad' messages went away.

My system is a freshly installed Proxmox 8.3, running on a Hetzner AX162-S:
