Bug Description

Binary package hint: apt

Manual purge of an old set of kernel files did not totally clean out the /lib/modules/2.6.32-10-generic directory, leaving file modules.builtin.bin. Noticed that a previous kernel ...9 removal left the same file and directory.

I just tried to reproduce this problem with
$ sudo apt-get purge `apt-cache pkgnames | fgrep 32-12`
but it did not crash for me. Do you have more crashes with apt?

Changed in apt (Ubuntu):
status:	New → Incomplete

The crash apparently happened on the 32-9 manual remove too. The 32-9 and 32-10 removals were the only ones I have seen with the error. I do not even see the modules.buildin.bin in my 9.10 system. At some point, I lost the graphics on the Lucid alpha, so I deleted it. The Lucid installation was on a 4G usb stick, so maybe a slow file system exposed a race condition, but
I have not seen this type of error on the many other usb sticks with Intrepid, Jaunty, and Karmic.

Here's another incomplete purge of kernel files, which did not cause a crash (different file this time, modules.seriomap).
This installation was on a hard disk, in a usb 2.0 enclosure.

Intrepid patched to date March 10, 2010 showed the manual kernel cleanup
problem. Same file, modules.seriomap was left.
No proprietary drivers in use.
