Bug#851790: installation-reports: DNS not working
Package: installation-reports
Severity: grave
Tags: d-i
Justification: renders package unusable
Dear Maintainer,
The current installer, with the new 4.9 kernel, is unable to resolve
domains, so is quite seriously broken.
This was noted during install on an arm64 gigabyte MP30-AR1
desktop/server, when choose-mirror failed, but it soon became clear
that DNS was not working.
Testing on an x86 VM with the same daily image (18th Jan 2017) found
the same problem. Going back to the rc1 installer image (4.8 kernel)
it works OK.
Tests showed that the network came up fine and things are pingable by IP, but not name:
# ping wookware.org
ping: bad address 'wookware.org'
# ping 93.93.131.118
PING 93.93.131.118 (93.93.131.118): 56 data bytes
64 bytes from 93.93.131.118: seq=0 ttl=50 time=19.892 ms
similarly the failing line from the choose-mirror log works if an address is inserted:
Jan 18 17:04:11 choose-mirror[31201]: DEBUG: command: wget --no-verbose http://debian-mirror.cambridge.arm.com/debian/dists/stretch/Release -O - | grep -E '^(Suite|Codename|Architectures):'

2017-01-18 17:47:12 URL:http://10.1.194.51/debian/dists/stretch/Release [177979/177979] -> "-" [1]
resolv.conf is as expected:
search cambridge.arm.com
nameserver 10.1.2.24
nameserver 10.1.2.23
(adding nameserver 8.8.8.8 makes no difference)
Watching packets go by when doing a VM install it is clear that the
local DNS server returns the correct response, but this is being ignored
or lost by the D-I initrd.
attached is an strace of strace ping wookware.org > /tmp/tracelog 2>&1
That gets a response from the server OK, but then goes on to ask the
other one. a working strace then uses the provided IP address. So
there is nothing obviously going wrong there.
