Update Open Office on Feisty Fawn

[Gunawan]

Hi All,
As we know that Feisty Fawn comes with Open Office 2.2.0.
I would like to upgrade to 2.3.0 so I have download it from openoffice.org.
Tar balls file contain many rpms. as advice by someone on ubuntu forums
I run alien command to convert it

sudo alien -d --scripts *.rpm

and then install it with dpkg

sudo dpkg -i *.deb

but when installing desktop integration I've got this error

joe at joe-desktop:~/temp/OOG680_m5_native_packed-1_en-US.9221/DEBS/desktop-integration$ 
ls
openoffice.org-debian-menus_2.3-9215_all.deb
joe at joe-desktop:~/temp/OOG680_m5_native_packed-1_en-US.9221/DEBS/desktop-integration$ 
sudo dpkg -i *.deb
