Subject: Cannot install on a custom kernel

Package: gspca-source
Version: 01.00.20-1
Severity: grave
Justification: Makes package uninstallable

Hi,

I just tried installing the gspca kernel module using module-assistant. I use
a custom kernel, downloaded straight from kernel.org, compiled and
installed myself, and because the kernel module package *depends* on a
kernel, the package installation fails for me:

    dpkg -Ei /usr/src/gspca-modules-2.6.24.2_01.00.20-1_i386.deb 
    Selecting previously deselected package gspca-modules-2.6.24.2.
    (Reading database ... 178712 files and directories currently installed.)
    Unpacking gspca-modules-2.6.24.2 (from .../gspca-modules-2.6.24.2_01.00.20-1_i386.deb) ...

     gspca-modules-2.6.24.2 depends on linux-image-2.6.24.2 | kernel-image-2.6.24.2; however:
      Package linux-image-2.6.24.2 is not installed.
      Package kernel-image-2.6.24.2 is not installed.

     dependency problems - leaving unconfigured
    Errors were encountered while processing:
     gspca-modules-2.6.24.2

I had a quick look at other packages that provide -source packages (for
example rt2500), and it looks like the kernel packages should be recommended, not
depended on. I include a patch to fix this below:

gspca-source is installable just fine ;-)

Sarcasm aside, I partially agree with you, but do not agree with the severity
considering the justification given. My reasoning is below.

Not the various module packages I maintain, personally I like to hard depend
to make removal of all kernel _and_ modules a pleasent experience.

There is no policy or best practise for this situation, only opinions, as far as I know.

Your patch will be applied immediately, but I do not know when the next upload
will be.

Thanks, Kel.

Subject: gspca has been removed from Debian, closing #481752

Date: Tue, 04 Aug 2009 23:17:37 +0100

Version: 01.00.20-1+rm

The gspca package has been removed from Debian so we are closing
the bugs that were still opened against it.

For more information about this package's removal, read
http://bugs.debian.org/519463 . That bug might give the reasons why
this package was removed, and suggestions of possible replacements.

Don't hesitate to reply to this mail if you have any question.

Thank you for your contribution to Debian.

Kind regards,
