Comment 4 for bug 950183

Yeah, that does the trick. Replace "puppet config print" in the postinst with "puppet --configprint" and this bug can be resolved:

root@host:/etc# dpkg -i puppetmaster-passenger_2.7.11-1_all.deb
Selecting previously unselected package puppetmaster-passenger.
(Reading database ... 25803 files and directories currently installed.)
Unpacking puppetmaster-passenger (from puppetmaster-passenger_2.7.11-1_all.deb) ...
Setting up puppetmaster-passenger (2.7.11-1) ...

Maybe someone else knows why the error is still in the output though?
