Java plugin lost after upgrade to 3.6.6 on 8.04 LTS

Asked by kaddidle

I recently upgraded Firefox to 3.6.6 on Ubuntu 8.04 LTS. Since then, I haven't been able to get the Java plug-in to work.

"about:plugins" does not list Java as a plug-in even though it looks like all the "*-javaplugin.so" files are installed.

sun-java6-jre and sun-java6-plugin are installed and I have restarted Firefox several times.

ok then run:

mkdir ~/.mozilla/plugins; cd ~/.mozilla/plugins/; ln -s /usr/lib/jvm/java-6-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so

Then restart your browser, should be ok

Tried adding the link and didn't work. Also tried adding the link to ~/.mozilla/plugin/ which also didn't work. Are there any other directories where Firefox might be looking for plug-ins?

How did you get Firefox 3.6.6 installed?

Upgrade from the Synaptic Package Manager.

If it helps, the first line in "/usr/share/doc/firefox-3.0/changelog.Debian.gz" is:

firefox-3.0 (3.6.6+nobinonly-0ubuntu0.8.04.2) hardy-security; urgency=low

Try this

gksudo gedit /etc/apt/sources.list

add these 2 lines to the bottom of the file:

deb http://ppa.launchpad.net/ubuntu-mozilla-daily/ppa/ubuntu hardy main
deb-src http://ppa.launchpad.net/ubuntu-mozilla-daily/ppa/ubuntu hardy main

Save the new file and close gedit

Then run:

sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 247510BE && sudo apt-get-update; sudo apt-get upgrade

Will give you 3.6.8 and may be friendlier.

Did not solve the problem, but received the following update which did solve the problem:

sun-java6 (6.20dlj-0ubuntu1.8.04.1) hardy-security; urgency=low

  * Fix LP: #600642:
  * Clean up the libjavaplugin_oji.so alternative on upgrade, as the OJI
    plugin is not compatible with Firefox 3.6.
    - add debian/JB-plugin.preinst.in
  * Bump the priority of the libnpjp2.so alternative, so it is selected in
    favour of other Java plugins which don't work with the new Firefox version
    - update debian/rules
