Thank you for explaining. I am struggling with this idea since AFAIK
the DNS servers have not been changed in the last six months or more
so I can think of no reason for the behaviour to have changed.
That history is what makes me think something must have changed in
the installer around the time of the last point release (May).
But from what you say that isn't the case.
You've given me a few things to try out
- tell DHCP to supply different DNS servers (running bind)
- make sure all ipv6 related options are disabled
and no ipv6 DNS entries exist for the target host
- make sure all ipv6 related options are enabled
and valid ipv6 DNS entries exist for the target host
Also I can try installing oldstable with the jessie installer.
If all of that makes no difference, what would be the next step?
I assume I'd have to build a debug version of the installer
and try to get a backtrace?
My concern is there's a segfault still lurking in the stretch
version. If we can squash it here that fix could be forward-ported.
Kind regards
Vince
