"This is not a genuine Ubuntu package"

blogged: apport: "This is not a genuine Ubuntu package" (the current Linux kernel package)

bug report · I made the mistake of assuming the kernel version shown by apport was the current kernel. I knew the running kernel was current, but I had just rebooted for the first time after the upgrade, and apport was reporting on an error in the previous version, which presumably had happened on shutdown.

The real bug here is that apport reports on errors about old packages without warning the user that they are old.

Launchpad bug report: After a kernel oops apport-gtk fails with "This is not a genuine Ubuntu package" (the current kernel package).

Binary package hint: apport

apport started on login due to a kernel oops immediately after an apt-get upgrade, and then quit with:

Problem in linux-image-2.6.32-20-generic
The problem cannot be reported:
This is not a genuine Ubuntu package

The package linux-image-2.6.32-20-generic is current.

No proprietary drivers are in use.
