Script that copies files/folders doesn't work

Hello, I recently signed up at Linode, deployed Ubuntu and installed Apache, Mysql and PHP5.

I'd actually made the change from a shared server to a vps in order to make an add-on for OsCommerce work. This add-on called Automatic stores generation (contribution at 14 May 2009) copies existing files and folders and this requires a LAMP environment with 'permissions of systems administrator'.

Unfortunately the script doesn't copy the files and folders.

Strange enough, the copying did work on the shared server. (symlinks didn't work there)

I just transferred all the files and sql data from the shared server to the Linode, edited config files and set all permissions to 777. (inc. public_html)

So now I'm wondering what needs to be done to make the script work. Some questions:

* • Is it also considered a LAMP environment when one uses Ubuntu? Are there differences for the functioning of scripts?

• What would be considered 'permissions of systems administrator' in this context? Like file permissions of 777?

• Are there necessary things I need to install on the server to get these kinds of things to work? For instance, I once had to install cURL.

• Would the script need a 'raw url' with the server name etc, rather than the url of the domain name? (like: /srv/www/domain.com/public_html) This 'raw url' was used in the config script on the shared host, but I don't know how this works.</list> 

I can't think of other reasons. Maybe you can?

Any advice is greatly appreciated!
