sudo apt-get install unzip build-essential x11-utils rpm ksh lsb-rpm libaio1 As of Ubuntu 9.10, libstdc++ 5 has been replaced by version 6. Below is how to fix the problem: wget http://mirrors.kernel.org/ubuntu/pool/universe/g/gcc-3.3/libstdc++5_3.3.6-17ubuntu1_amd64.deb dpkg-deb -x libstdc++5_3.3.6-17ubuntu1_amd64.deb ia64-libs cp ia64-libs/usr/lib/libstdc++.so.5.0.7 /usr/lib64/ cd /usr/lib64/ ln -s libstdc++.so.5.0.7 libstdc++.so.5 wget http://security.ubuntu.com/ubuntu/pool/universe/i/ia32-libs/ia32-libs_2.7ubuntu6.1_amd64.deb dpkg-deb -x ia32-libs_2.7ubuntu6.1_amd64.deb ia32-libs sudo cp ia32-libs/usr/lib32/libstdc++.so.5.0.7 /usr/lib32/ cd /usr/lib32 ln -s libstdc++.so.5.0.7 libstdc++.so.5 Note: The package names in Ubunto differ from RHEL and the OUI system check will report several missing. You can ignore them, but you will probably need to install some or all of the following packages first: sudo su - apt-get install build-essential apt-get install libaio1 apt-get install libaio-dev apt-get install libmotif3 apt-get install libtool apt-get install expat apt-get install alien apt-get install ksh apt-get install pdksh apt-get install unixODBC apt-get install unixODBC-dev apt-get install sysstat apt-get install elfutils apt-get install libelf-dev apt-get install binutils apt-get install lesstif2 apt-get install lsb-cxx apt-get install lsb-rpm Btw, to make the arrow-keys work properly in 'vi': apt-get install vim-runtime apt-get install vim To make ssh work: apt-get install ssh passwd oracle In case someone else runs into the same issues...... cp ia-libs/usr/lib/libstdc++.so.5.0.7 /usr/lib cd /usr/lib ln -sf libstdc++.so.5.0.7 libstdc++.so.5 # ln -s /usr/bin/awk /bin/awk # ln -s /usr/bin/rpm /bin/rpm # ln -s /usr/bin/basename /bin/basename # mkdir /etc/rc.d # for i in 0 1 2 3 4 5 6 S ; do ln -s /etc/rc$i.d /etc/rc.d/rc$i.d ; done # mkdir -p /u01/app/oracle # chown -R oracle:dba /u01
