2.6.28-10-generic looks like a superseded package that did not properly clean up after itself

[Rolf Leggewie (r0lf)]

Still an issue for the karmic kernel.

All of the kernel listed above had been purged from my system.

Hi Rolf,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid.

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 374105

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

[Rolf Leggewie (r0lf)]

come on, this is easy enough to test for yourself. No need for automatic messages to see that this still exists.

[Brad Figg (brad-figg)]

This bug was filed against a series that is no longer supported and so is being marked as Won't Fix. If this issue still exists in a supported series, please file a new bug.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Rolf Leggewie (r0lf)]

I don't quite see the point of opening a new bug rather than reopening this one. Neither 2.6.32-20-generic nor 2.6.32-21-generic are installed on my computer any longer. Maybe this is a problem in the backports-modules package?

[Rolf Leggewie (r0lf)]

Yes, very much looks like the linux-backports-modules-wireless packages are to blame. When trying to purge them I get

dpkg: warning: while removing linux-backports-modules-wireless-2.6.32-20-generic, directory '/lib/modules/2.6.32-20-generic/updates' not empty so not removed.

Purging them fails anyhow, that will be another bug to report.

[Rolf Leggewie (r0lf)]

It seems like something else is at play here also.

All the /lib/modules/2.6.3?-41-generic/ directories are basically empty except for that single link. More leftover cruft despite those kernel image packages being purged.

The 2.6.32-2* kernels apparently left some stuff behind due to linux-backports-modules-wireless packages as previously mentioned.
