My experience were approx the oposite ..
I tried for 20 times or so to install the e-smith variant. It did not work because I were not able to configure the database right. So in the end I gave it up and downloaded the "orginal version".
I just followed the instructions at the home page and it went stright in without a problem. Have tested for a while together with a friend tonight. Seems to be working most of the functions, exept for the e-mail ... Don't know really how it should work, (Have not tried this groupware before.
I believe that the e-smith installation and the orginal installation is so different so it can not really be a upgrade but a complete new intstallation. (Reason: Seems like the structure and the location of the files is rather different.)
By the way .. I have rather big problems concerning the removal of the e-smith rpm. If i try to upgrade or ask with a rpm -q it says that the rpm is there. If I try to remove it it just says it's not there, so I can't get it in or get it out, just something just beween asd some kind of "file garbage". Do you have any ideas how to remove the remaining of the sme rpm ?? (I don't like to know that there is som e "hidden problems" even though the other variant seems to be working.)
This page plus the faq page were the only documents I have needed so far:
