Huh? What's with the sudo for dpkg -S?
For all I remember that works fine without root privileges.

olaf@quark:~$ find /usr/bin -atime +360 | xargs -l1 dpkg -S \
| awk -F ':' '{print $1}' | sort | uniq

FWIW, throwing in sudo gives the same result and my user account is in
the sudo group. And I have modified that groups /etc/sudoers entry to

 # Allow members of group sudo to execute any command

so it doesn't prompt me for a password.

Hope this helps,
