BUG in Debian SID

[Łukasz Kalamłacki <kalamlacki@gmail.com>]

Hello,


I detected and issue with Debian SID and DHCP for IPv6.


In my network I use DHCPv6 server which works fine on stable versions of 
Debian or Trixie but when I add to sources.list sid source and do update 
and upgrade I get and error that:

"Link local ipv6 for interface is not configured" in syslog and 
systemctl is reporting failed networking service and only ipv4 
addressing is available.


configuration in /etc/network/interfaces

auto enp0s3

iface enp0s3 inet dhcp

iface enp0s3 inet6 dhcp


What is interesting when the system is already running I can do:

dhclient -6 enp0s3

and I get ipv6 address correctly


The problem is reproducible on Virtualbox: just install testing Debian 
and add sid to source.list and do update/upgrade in apt.


The issue is very strange because during upgrade to SID I do not see 
installation of any networking packages.


What do you think?


Best regards,

Łukasz
