Thanks guys.  Just deleting the MY_HOSTID line didn't work. Neither
did just running dpkg-reconfigure popularity-contest (I had tried that

Looking at that postinst file you mentioned shows it matches the
md5sum of a .conf file with a blank MY_HOSTID rather than just
checking to see if it's there.  So rather than mucking around making
sure every space was in the right spot, I just deleted the whole
/etc/popularity-contest.conf file THEN ran dpkg-reconfigure
popularity-contest.  Tada!

Thanks again,

PS  and my guess was right - it does use uuid
