Title:
  "Temporary failure in name resolution" failures in chroot during
  install.

Status in debian-installer package in Ubuntu:
  Confirmed

Bug description:
  On an artful netboot install, the chroot target cannot resolve any
  hostnames and fails to fetch and install packages.

  $ ping <hostname>: Temporary failure in name resolution

  This is somehow related to the symlinking of /etc/resolv.conf.

  # ls -l /etc/resolv.conf 
  lrwxrwxrwx 1 root root 29 Aug 25 21:05 /etc/resolv.conf -> ../run/resolvconf/resolv.conf

  # ls -l /run/resolvconf/resolv.conf
  lrwxrwxrwx 1 root root 39 Aug 25 21:04 /run/resolvconf/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf

  # ls -l /run/systemd/resolve/stub-resolv.conf
  -rw-r--r-- 1 root root 89 Aug 25 21:04 /run/systemd/resolve/stub-resolv.conf

  # cat /etc/resolv.conf 
  cat: /etc/resolv.conf: No such file or directory

  However, if I replace /etc/resolv.conf with an actual file with the
  contents of /run/systemd/resolve/stub-resolv.conf, then I can resolve
  hostnames again.
