Potential problem of breaking APT operations is much more dangerous than 
"actual" problem of ignoring return values.

That's right. Script was not intended to be used directly to begin with.
It was designed to be run automatically at the end of APT operations and 
(re-)build passenger package when required.

Perhaps to temporary break script to always return error value and try 
various apt operations (e.g. install, remove and reconfigure of other 
packages) when post-invoke hook is activated to perform build or update.

We need to be absolutely sure that build/install errors do not propagate 
where they does not belong and that nothing got broken if we take 
responsibility for propagation of those errors.

Best wishes,

Without doubt you are not sane.
