Bug#807371: apt hostname resoloution failure
Package: apt
Version: 1.1.3
Severity: grave
When running apt in a Debian stretch armhf chroot on my odriod u2 DNS
resoloution fails. ping is able to resolve the hostname.
root@odroidu2:/# apt-get update
Err:1 http://mirror.bytemark.co.uk/debian stretch InRelease
Could not resolve 'mirror.bytemark.co.uk'
Reading package lists... Done
W: Failed to fetch
http://mirror.bytemark.co.uk/debian/dists/stretch/InRelease Could not
resolve 'mirror.bytemark.co.uk'
W: Some index files failed to download. They have been ignored, or old
ones used instead.
root@odroidu2:/# ping mirror.bytemark.co.uk
PING mirror.bytemark.co.uk (212.110.161.69) 56(84) bytes of data.
64 bytes from mirror.bytemark.co.uk (212.110.161.69): icmp_seq=1 ttl=57

The chroot is on a host system running a vendor 3.0.90 kernel, no idea
if that is relavent. At the very least if there is a problem running on
older kernels there should be a warning before the updated packages are
installed.
The issue seems to be new in the 1.1 series of apt versions.
The issue definately seems to be somehow related to dns lookups. If I
add the hostname to /etc/resolv.conf then apt seems to work.
Any thoughts on how to debug this.
