package cups 1.5.2-9ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

My computer froze ( I believe bad hard drive) while configuring my printer, then after rebooting, it showed error message when trying to change printer settings and would not connect to localhost for cups to start.

The error report shown above came because i thought I would fix it by removing and then adding cups. It was upon installing cups that this error was reported.

Status changed to 'Confirmed' because the bug affects multiple users.

pitti, seems to be an upstart problem. Can you have a look ? Thanks.

[Martin Pitt (pitti)]

The log says

X [16/Apr/2012:23:59:17 -0700] No valid Listen or Port lines were found in the configuration file.

so it seems you somehow damaged your /etc/cups/cupsd.conf ?

[Till Kamppeter (till-kamppeter)]

Problem caused by broken cupsd.conf.
