openjdk6 not available

Question

I run a server with Ubuntu 10.04 (Lucid Lynx) Minimal Server, on amd64 system. I 'd like to install the openjdk packages (jre and jdk), but when I try

sudo apt-get install openjdk-6-jdk

I get

Package openjdk-6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package openjdk-6-jdk has no installation candidate

And I 'd like to install this package andI don't know how, while it seems to be available here

Answer 1

Please try a sudo apt-get clean && sudo apt-get update after changing your software mirrors :)

Answer 2

Open a terminal and try these commands:

sudo add-apt-repository ppa:openjdk-r/ppa  
sudo apt-get update   
sudo apt-get install openjdk-6-jre 

Answer 3

the error says "the package ....or is only available from another source"

Check your sources.list, see if it contains a non-standard ubuntu server.

Answer 4

Oracle has stop providing oracle 6 and 7 jdk. And to install older version, need to use offline installation method.

First download oracle-jdk7-installer.tar.gz and oracle-java7-installer_7u80+7u60arm-0~webupd8~1_all.deb

cp -r oracle-jdk7-installer.tar.gz oracle-java7-installer_7u80+7u60arm-0~webupd8~1_all.deb /var/cache/
cd /var/cache
tar -xvf oracle-jdk7-installer.tar.gz
dpkg -i oracle-java7-installer_7u80+7u60arm-0~webupd8~1_all.deb
