not all package install failures generate a crash report

Bug Description

I was trying to install the package crash-in-postinst package from the following PPA, This package is specifically designed to fail during the post installation due to a maintainer script error. I was surprised to discover that software-center did not create a package install failure crash file in this case. I did receive an error message from aptdaemon that said the "Package operation failed". Digging into the software-center code I found the following:

        # lintian errors are ignored and not send to apport_recoverable_error
        # and dpkg errors as well as they will already be recorded separately
        # by apt itself
        if error_code in (enums.ERROR_INVALID_PACKAGE_FILE,

For some reason these errors are not being recorded when the package manager has failed. However, if one uses 'apt-get install' or 'aptdcon' to install the same package you will get a crash report. So I believe it is something with software-center itself that is preventing these crash reports from being generated.

Apport provides a package_hook script, /usr/share/apport/package_hook, for creating package install failures so we could call that from software-center. I've written a patch that does just that.

Here is an incomplete patch using the package_hook utility to create .crash files. However, there is an issue with the naming of attachments and code in the general Ubuntu hook ( for handling dpkg log files. The issue being that the log file will be called VarLogAptTermlog and not DpkgTerminalLog like expects.

If fixing this is likely to change the reported error rate without changing the actual error rate, these particular error reports should include the DetectedSince key.
