I have been following this (http://www.pythian.com/news/968/installing-oracle-11g-on-ubuntu-804-lts-hardy-heron/) tutorial. I used exact same Ubuntu version and Oracle 11g (chcksum and MD5 verified)Everything went alright up to the final stage of starting up the setup. when the setup attempt to run it get me following error

i gone though this same procedure on brand new ubuntu installations three times but still getting this error.
for all this operation I'm using Oracle Virtual Box.

Any helpful tips?

This article clearly describes installation of Oracle 11g release 2 on Ubuntu desktop (Posted on 03-December-2011)

Steps are same for 8.04. I recommend you to upgrade to 10.04 since it is a long term support version before trying Oracle. good luck !
