Kubuntu 9.10 (karmic) 64bit firefox java plugin
For some unknown reason the (K)Ubuntu developers did not update the Java plugin for firefox after jaunty (yet?).
The version that Karmic (9.10) pulls out of the multiverse repository is still jaunty's (9.04).
So when you try:
apt-get install sun-java6-plugin
you'll get something like
Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: sun-java6-plugin: Depends: sun-java6-bin (= 6-15-1) but 6-16-0ubuntu1.9.04 is to be installed E: Broken packages
Duh.
Actually if you have the Java Runtime Environment (JRE, package name sun-java6-jre
) installed all files needed are already present.
Just not put in the right place on the filesystem.
So, run:
sudo apt-get install sun-java6-jre # install JRE if needed
sudo ln -s /usr/lib/jvm/java-6-sun/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/
sudo ln -s /usr/lib/jvm/java-6-sun/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/
This will install the JRE (if it's not already installed) and will symlink the firefox plugin for java in place so that it'll be found after a browser restart.
