Bug#1015809: 1015809: isc-dhcp-client: DHCPv6 doesn't work on ppp interface, got `Unsupported device type` error

[Steven Haigh]

I don't run Debian on that system anymore due to other issues I came 
across - however, if I can extract the dhclient binary, I can probably 
test that on my current setup. That was my workaround using the Fedora 
dhclient binary for a while on the Debian install.

 I know IPv6-PD isn't really wide-spread, but its enough that there 
should be

 at least one functional method to do it within Debian.


Regarding IPv6-PD in stable, I am preparing an upload, but I am unable
to actually test it. Are you able to give it a try?

At that point, you're right - it'll probably not get much attention 
again afterwards.

 wide-dhcpv6-client doesn't seem to interpret the reply from the ISP

 dibbler-client binds to the wrong LL address and fails to open a

 Copying the dhclient binary from a Fedora 38 install and using that
 works perfectly - which is using the Fedora patches for dhclient 
v4.4.3.


 The current, functioning patch from Fedora is here:

 How are we able to fix this properly instead of a 'copy the binary 
from

 Fedora' type fix?


Sorry, I really missed this bug report. That said, since the EOL of
isc-dhcp-server, I reduced the priority given to isc-dhcp.

If isc-dhcp is that broken for .au, I could consider a stable update,
after this has been solved in unstable and confirmed doesn't break
anything.

It looks like this report is over a year old - but there's been no 
movement on it.


It seems that a PD request won't work on Debian 12 either using 4.4.3.

Is there any reason as to why this patch hasn't been added?
