Installing OSB 10.3.4 on Ubuntu

The installation was not free from problems:

It is very well documented here:
http://soa-playground.blogspot.com/2011/03/oracle-service-bus-osb-on-ubuntu-linux.html

but something must be added:

ignore the warning you get about the insufficient swap space:

Starting Oracle Universal Installer...

Checking if CPU speed is above 300 MHz. Actual 2094 MHz Passed
Checking Temp space: must be greater than 150 MB. Actual 10273 MB Passed

just say yes...

just ignore the message "sh: /bin/rpm: not found"

Plenty of prerequisite checks fail... I could not find a way to display the cause of their failure. Yet if you click on the upper button (ignore the lowermost ones) "continue" the installation proceeds without other issues.... weird...
