The Goal

Upgrading ubuntu using alternate ISO without having to burning it to the CD. We mount the ISO manually and install from there.

The Process

Important, upgrading an ubuntu require you to do it in sequence manner. For example, if your current version is Ubuntu 8.04 and you want to upgrade to Ubuntu 9.10 you must upgrade to 8.10 first, then 9.04 and finally 9.10. This tutorial cover upgrading from Ubuntu 9.04 to 9.10. So, here we go.

Pre-Installation

You must have Java Development Kit (JDK) installed first, refer to this article if you not install the JDK yet.

The Goal

You can install Sun JDK on Ubuntu Linux using "unpack and run" method not via apt-get.

The Process

1. Download the Sun JDK for Linux from http://java.sun.com/
2. Open the terminal to extract the package, move to the saved location first: (I assume you save it to your home directory) $ cd /home/user $ sh jdk-6u7-linux-1586.bin
3. You will be asked "License Agreement" and type yes to Agree. $ sudo mv jdk1.6.0_07 /usr/local $ sudo ln -s /usr/local/jdk1.6.0_07 /usr/local/java
4. Check the current java that running on your system $ update-alternatives --list java /usr/bin/gij-4.2
5. After running that command we knew that there is no alternative for java. So, we need to add our new JDK to the alternatives.
