cron-apt configuring

Hi, I use this tutorial for cron-apt configuring http://www.turnkeylinux.org/docs/automatic-security-updates Looks like something wrong. First of all I didn’t get the mail with update log and have some errors in cron-apt log file.

CRON-APT RUN [/etc/cron-apt/config]: Mon Jul 1 04:00:01 UTC 2013 CRON-APT SLEEP: 2050, Mon Jul 1 04:34:11 UTC 2013 CRON-APT ACTION: 0-update CRON-APT LINE: /usr/bin/apt-get -o quiet=1 update -o quiet=2 W: GPG error: http://archive.turnkeylinux.org lucid-security Release: The following signatures couldn’t be verified because the public key is not available:$ CRON-APT ACTION: 3-download CRON-APT LINE: /usr/bin/apt-get -o quiet=1 autoclean -y Reading package lists… Building dependency tree… Reading state information… CRON-APT LINE: /usr/bin/apt-get -o quiet=1 dist-upgrade -d -y -o APT::Get::Show-Upgraded=true Reading package lists… Building dependency tree… Reading state information… The following NEW packages will be installed: linux-image-3.2.0-48-virtual The following packages will be upgraded: apt apt-utils … … xkb-data 119 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.

Is this log ok? And does it mean that upgrade all new packages or secure updates only?
