E: The package ohai-solo needs to be reinstalled, but I can't find an archive for it.

I checked ubuntu archives and no archive exists for 12.04 release...

This is unrelated to Filebeat. Your ohai-solo package is probably in a half-installed state, and when you try to install Filebeat it tries to fix your ohai-solo installation too, but fails. Try uninstalling ohai-solo first.
