Comment 5 for bug 1325142

Today a package upgrade to whoopsie in 14.04 is also triggering the same missing init.d script problem.

Preparing to unpack .../whoopsie_0.2.24.6_i386.deb ...
invoke-rc.d: unknown initscript, /etc/init.d/whoopsie not found.

E: Sub-process /usr/bin/dpkg returned an error code (1)

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I assume the same hack of editing the pre/post inst/rm scripts to exit with a warning and 0 exit code instead of $? can temporarily work around it.
