package openjdk-6-jdk 6b22-1.10.2-0ubuntu1~11.04.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 127

[SilverFox]

Error occurred whilst re-installing Eclipse application. Had problems installing 11.04 from installation disc (clean installation). Upon a bootable attempt, backup files were recovered using "Simple Backup-Restoration." Restored paths, directories and files included were /etc, /var, /home and /usr/local. When re-installing software applications that I had installed before, the Ubuntu Software Centre showed all applications I had installed before as "installed" with a tick. The only way I thought I could resolve this issue was to un-install each application and re-install them again.
