prerm/postinst scripts failing silently(?)

[Serafeim Zanikolas]

Hi all,

I'm adopting a package that produces several binaries, and I need to adapt it
so that every binary will have its own prerm and postinst scripts (issue
#315318). I tried calling the scripts debian/binaryX.{prerm,postinst}, but
they seem to be ignored when installing the binary packages (postinst calls
update-alternatives but there is no sign of it actually being called), and I
don't see any error messages when installing the package by hand). Attached
are the scripts for one of the binaries.

Any hints on how I could debug this?

Cheers,
Serafeim
