Comment 8 for bug 409559

Repost, this time without tags that don't work (sorry!):

You can apply a workaround to install the new JRE which is meant for Karmic, in Hardy, Intrepid and Jaunty.

This workaround is for 32-bit Ubuntu only! You have to adapt it for a 64 bit system.

1. Manually download these three files from Multiverse:

Bin:
http://nl.archive.ubuntu.com/ubuntu/pool/multiverse/s/sun-java6/sun-java6-bin_6-15-1_i386.deb

JRE:
http://nl.archive.ubuntu.com/ubuntu/pool/multiverse/s/sun-java6/sun-java6-jre_6-15-1_all.deb

Plugin:
http://nl.archive.ubuntu.com/ubuntu/pool/multiverse/s/sun-java6/sun-java6-plugin_6-15-1_i386.deb

2. Put these files in your home folder, don't leave them on the desktop.

3. Applications - Accessories - Terminal
Execute the following terminal commands (use copy/paste to place them in the terminal):

sudo dpkg -i sun-java6-bin_6-15-1_i386.deb sun-java6-jre_6-15-1_all.deb

Press Enter. Your password will remain invisible, not even dots, this is normal.

and then:

sudo dpkg -i sun-java6-plugin_6-15-1_i386.deb

Press Enter.

4. Ready. :)

Bad that we need a workaround... We shouldn't need one. The package maintainer isn't active enough. :(
