Comment 2 for bug 1577966

This bug was fixed in the package autopkgtest - 3.20.6

---------------
autopkgtest (3.20.6) unstable; urgency=medium

  * Fix OSError when running a shell is requested but /dev/tty does not exist;
    just log an error instead.
  * Fix parsing of candidate versions from "apt-cache policy" to always use
    the precise given package name. By default it falls back to a
    substring/regexp search (undocumented).
  * adt-build-lxd: Check the LXD configuration for the LXD bridge instead of
    the old LXC bridge, for apt proxy auto-detection. (LP: #1577968)
  * Generalize the apt proxy detection in adt-build* and setup-testbed to
    work for arbitrary proxies, not just apt-cacher-ng. (LP: #1577966)
  * Eliminate the need to set $AUTOPKGTEST_BASE to execute runner/adt-run from
    a git checkout. This also makes ./run-from-checkout obsolete, call
    runner/adt-run directly.
