make_report_path missing (called from dkms_packages.py)

[Mike C. Fletcher]

When upgrading Kernel on Kubuntu 15.04 with a package that fails to build against the current kernel, the apport dkms hook fails to report the bug.

The file:

    /usr/share/apport/package-hooks/dkms_packages.py

is provided by the package dkms. Either the hook should be using a public API, or if this is/was a public API it should be kept stable for external hooks, if it's not a public API then likely should re-assign to dkms with note on what API should be used, otherwise should provide the missing API in apport.

/var/log/apport.log is empty, .crash file is included below.
