Not sure, does it require MS2.2?
I stopped allowing the updates because is was an old version and replace the version stored with a MS2.2 version.
I posted an upgrade script somewhere on the forums but cannot locate it.
# uposCommerce.sh
#
# Update the cPanel addon installation package for osCommerce to the
# version in the URL. Currently MS2-2.2 7-12-2003
#
# This script will download the version from sourceforge then unpack,
# and create a pkg.tar.gz for the cPanel install program to use
#
# Change the URL if you want a different snapshot
URL=http://heanet.dl.sourceforge.net/sourceforge/tep/oscommerce-2.2ms2.tar.gz
# Location cPanel keeps our pkg.tar.gz for the installs
cPanelDir=/usr/local/cpanel/addons/osCommerce
# I bulid the package in /tmp
cd /tmp
wget $URL
# Unpack it ....
tar zxvf oscommerce-2.2ms2.tar.gz
DIR=/tmp/oscommerce-2.2ms2
mkdir /tmp/os
mkdir /tmp/os/catalog
mkdir /tmp/os/admin
cd $DIR
cp -r catalog /tmp/os/catalog
cd catalog
# The admin directory needs to be its own directory for the pkg.tar.gz
cp -r admin /tmp/os/admin
# We do not need the admin directory in the catalog directory
rm -rf /tmp/os/catalog/catalog/admin
mv /tmp/os /tmp/pkg
cd /tmp
tar cvfz pkg.tar.gz pkg
# Now put it in the /usr/local/cpanel/addons/osCommerce directory
cp $cPanelDir/pkg.tar.gz $cPanelDir/pkg.tar.gz.oldcp pkg.tar.gz $cPanelDir
# Clean up the temporary files I just created
rm pkg.tar.gz
rm -rf pkg
#
# End
#
You could get just about any version you want. If you want the most current just change the top of the script.
