In one of my earlier posts I had shown how to install Sun Java6 on Ubuntu(Karmic). When I upgraded to Lucid recently, that version of JDK was removed and Open JDK was the only one that was present. I had to google a bit to realize that sun-java6 was no longer present in the repositories. The release notes on Ubuntu’s wiki state the same. However, following the instructions on the release notes did not help me. Two reasons… First, the link is incorrect and secondly, the sources.list needs to have two entries one for deb and another for deb-src. The command on the wiki just adds the line with deb on the sources.list.
I found this blog that has a better explanation of the steps to be followed to fix the problem.
Uncomment the following two lines.
deb http://archive.canonical.com/ubuntu lucid partner
deb-src http://archive.canonical.com/ubuntu lucid partner
Run the following commands
sudo aptitude update sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk sudo update-java-alternatives -s java-6-sun
