Oracle 11g install problem on Ubuntu I ran the runInstaller script in the root dir of the extracted zip files. After some pages of the graphical installer it sent me to run 

/tmp/CVU_11.2.0.1.0_macbook/runfixup.sh


as root. It gave me the following errors:

What shall I do?
a) Use an OS that is certified for installing and running Oracle Database (Ubuntu is not amongst them). Native or virtual machine, your choice.

or

b) here is an unofficial guide for installing Oracle 11.2 on Ubuntu Linux

I have never tried myself, but several people succeeded installing Oracle 11.2 on Ubuntu with the help of this.
