Title:
  package resolvconf 1.79ubuntu10 failed to install/upgrade: installed
  resolvconf package post-installation script subprocess returned error
  exit status 1

Status in resolvconf package in Ubuntu:
  Confirmed

Bug description:
  During a "do-release-upgrade -d" from 16.04 to 18.04, an unrelated
  error occurred.  DNS didn't work at that time, so I removed
  resolvconf.  I manually updated my sources.list and did a successful
  dist-upgrade.  Then I tried to reinstall resolvconf, and got the error
  below.
