Hi,
I did further test on VirtualBox and on KVM.
VirtualBox on Linux somehow blocks IPv6 in bridged mode of the network
configuration, so I created VM on KVM in bridged mode of the network
brctl addbr bri0
brctl addif bri0 eth1
ifconfig bri0 up
connected cable rj45, because we cannot add to the bridge wlan iface
and after adding:
auto enp8s0
iface enp8s0 inet dhcp
iface enp8s0 inet6 dhcp
to /etc/network/interfaces
and added to /etc/apt/sources.list removing all other lines
deb http://deb.debian.org/debian/ sid main non-free-firmware
deb-src http://deb.debian.org/debian/ sid main non-free-firmware
and I did
apt update
apt full-upgrade
and everything works surprisingly.
But right now I have other issue with the system where previously I did
the update wrong way, because on that machine ipv6 still does not work
and after deleting everything besides sid from sources.lists and executing
apt update
apt full-upgrade
ipv6 fails.
Do you have solution for me?
Best regards,
Łukasz

Łukasz,
I wanted to do another try, but this time stay with the initial Debian
installation, that is not alter /etc/network/interfaces file.
So this time I just built Bookworm, then upgraded to Sid.
Good news is I still cannot replicate your issue. Hopefully the issue
was because of the non sid sources.
All the best with your fault finding, and thanks for the fun of
running up a couple of VMs. I really enjoy how VMs make testing easy.
Below is my checking after building the Bookworm VM, to upgrading to
sid, and then checking once again.

Hi,
Are you able to reproduce at your side? You can verify this on
VirtualBox even without DHCPv6 server. In normal circumstances you
should get timeout on dhclient but the BUG causes that Debian
should end immediately without timeout and with the error
mentioned in the first post in syslog.
So are you able to reproduce at your side?
Best regards,
Łukasz

Łukasz,
I wonder if the issue is that you are missing
"non-free-firmware" which provides the non-free drivers for
things like sound, network and WiFI devices?
(Hopefully you only have 'sid' sources and no sources for
other versions, for example 'bookworm' or 'backports')
It could help to at least add "non-free-firmware" even if
there is another issue?

Uncomment the deb-src line, if you want to enable the source
repos.
