Getting Error while installation

[Lokesh_Kamath]

Could not find the main class: org.nuxeo.launcher.NuxeoLauncher. Program will exit. [fail] invoke-rc.d: initscript nuxeo, action "start" failed. dpkg: error processing nuxeo (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: nuxeo E: Sub-process /usr/bin/dpkg returned an error code (1)

How to solve this?

I believe you get this message when Nuxeo is started with the wrong version of Java.
/> Can you change the default version on your system to be Java 7? ( sudo update-java-alternatives --set java-1.7.0-openjdk-amd64 )
