I had the same problem when upgrading.  In addition, a previous distro
competed with uids/gids in the 500 range; so I changed all my users to
start at 555.  Now, when upgrading, I create ONLY an "installer" userid,
then copy over all the /etc/{passwd,shadow,group} stuff in the 555+ range
(users only) and voila!
