What does "debconf: delaying package configuration, since apt-utils is not installed" mean?
apt-utils contains the /usr/bin/apt-extracttemplates program which is used when packages need to ask you questions about how to be configured. This package being Priority: important, means it should really be installed except in rare circumstances.
If there is configuration pending, dpkg-reconfigure [package] will perform it. If you missed configuring a number of packages and don't know which, run dpkg-reconfigure -au to go through (a)ll (u)nseen configuration questions.
