What does ' link group java is broken.' really mean and what is its resolution. I have been getting this message since I tried to install IBM Java.

I tried with option 0 also but the same result. Update-alternatives: warning: not replacing /usr/bin/java with a link. Update-alternatives: warning: forcing reinstallation of alternative /usr/lib/jvm/java-6-openjdk/jre/bin/java because link group java is broken. Press enter to keep the current choice, or type selection number: 2 * 0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto modeġ /opt/ibm/java/ibm-java-x86_64-60/jre/bin 1 manual modeĢ /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode There are 2 choices for the alternative java (providing /usr/bin/java). So I ran sudo apt-get install openjdk-6-jre and sudo apt-get install openjdk-6-jdk to at least let open jdk work. update-java-alternatives updates all alternatives belonging to one runtime or development kit for the Java language. In this whole process I have completely messed up and now no java version is working. Use update-java-alternatives to update java version Alternative, a dedicate command update-java-alternatives can also be used to switch java version.

Originally I installed Open JDK and then tried to install IBM Java based on some instructions on the web using tgz files I downloaded from IBM website (I need to be able to install websphere later).
