do-agent cron output

Since installing the new do-agent I get the following output from anacron: cron command: test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily

/etc/cron.daily/do-agent: debconf: unable to initialize frontend: Dialog debconf: (TERM is not set, so the dialog frontend is not usable.) debconf: falling back to frontend: Readline debconf: unable to initialize frontend: Readline debconf: (This frontend requires a controlling tty.) debconf: falling back to frontend: Teletype dpkg-preconfigure: unable to re-open stdin: (Reading database … 140933 files and directories currently installed.)

Is this indicating a problem? If not, how can I silence the output?

thanks
