#77713 — Upgrade of single Linux v6.1.0 (unsigned) package from Debian/experimental fails

Hi,

this was possible with linux-image-6.1.0-0-amd64-unsigned
(6.1~rc8-1~exp1) but fails now with linux-image-6.1.0-0-amd64-unsigned
(6.1.1-1~exp2):

...which packages is shipping sign-file?

OK, looks like you need kbuild-6.1 package, too.

root# cd /var/cache/apt/archives

root# dpkg --contents linux-kbuild-6.1_6.1.1-1~exp2_amd64.deb | grep sign-file
-rwxr-xr-x root/root     18920 2022-12-24 08:04
./usr/lib/linux-kbuild-6.1/scripts/sign-file

Might be good to have this as a Depends for linux-image (unsigned) and
why is `dpkg -S /path/to/sign-file` not showing the responsible
package?

Thanks.

Happy Xmas (if you celebrate it),

#77714

Sorry, here the relevant part of ERROR quote:

/etc/kernel/postinst.d/dkms:
dkms: running auto installation service for kernel 6.1.0-0-amd64:Sign

Binary /lib/modules/6.1.0-0-amd64/build/scripts/sign-file not found,
modules won't be signed

For an unsigned linux-image you do NOT need the sign-file binary:
Might be a DKMS issue?

linux-image shouldn't depend on linux-headers etc. as that would pull
in a lot of big packages that are completely unnecessary for users that
don't use OOT modules.

"dpkg -S" is easily confused by symbolic links.

We provide the linux-headers-<flavour> metapackages to make it easy to
get the new kernel headers and rebuild OOT modules.  By using
"APT::Get::Upgrade-By-Source-Package=0" you prevented APT from
upgrading linux-headers-amd64 together with linux-image-amd64.  Maybe
DKMS should have done a better job of reporting this, but it's really
your mistake.

Ben.
