I have installed all the packages availabe on the Ubuntu CDInstalling all packages is not necessary, but you will need to install the packages as described above in "Install required packages".
Package: glibc-2.3.4-2.41: This is a prerequisite condition to test whether the package "glibc-2.3.4-2.41" is available on the system.Oracle does not support Ubuntu, hence the prerequisite checks of the Oracle Universal Installer will not recognize debian based packages. You need to ignore the prereq failures as outlined.
server_address: Name or service not known"server_address" is not to be taken literally, but should be replace with the hostname or IP address of your Oracle server. Please check the provided information from Oracle and search google for burning an ISO image or creating a DVD and using the Oracle installer. The process is too complex and client OS specific to explain.
