Bug#910959: grub-cloud-amd64: missing Conflicts: grub-coreboot, grub-efi-ia32, grub-ieee1275, grub-xen

[Andreas Beckmann]

Package: grub-cloud-amd64
Version: 0.0.1
Severity: serious
User: ***@debian.org
Usertags: edos-file-overwrite

Hi,

automatic installation tests of packages that share a file and at the
same time do not conflict by their package dependency relationships has
detected the following problem:

Selecting previously unselected package grub-cloud-amd64.
Preparing to unpack .../6-grub-cloud-amd64_0.0.1_amd64.deb ...
Unpacking grub-cloud-amd64 (0.0.1) ...
dpkg: error processing archive /tmp/apt-dpkg-install-5Ao0pQ/6-grub-cloud-amd64_0.0.1_amd64.deb (--unpack):
trying to overwrite '/etc/kernel/postinst.d/zz-update-grub', which is also in package grub-coreboot 2.02+dfsg1-6

It's a bit unfortunate that the grub packages don't use
Provides+Conflicts+Replaces on a virtual package to ensure
only variant is installed. So you'll have to list all the packages
in your Conflicts.

Here is a list of files that are known to be shared by both packages
(according to the Contents file for sid/amd64, which may be
slightly out of sync):

etc/kernel/postinst.d/zz-update-grub
etc/kernel/postrm.d/zz-update-grub

This bug is assigned to both packages. If you, the maintainers of
the two packages in question, have agreed on which of the packages will
resolve the problem please reassign the bug to that package. You may
also register in the BTS that the other package is affected by the bug.

Cheers,

Andreas

You forget to actually assign it to both. Let's fix that first.

etc/kernel/postrm.d/zz-update-grub

Is there are particular compelling reason why this files needs to be
duplicated in all grub-* packages, instead of residing in
grub(2)-common? They are not even different from each other.

Given that it seems like this conflict is the only reason why two
variants are not cross-installable.

No answer is also an answer. So there is no real reason.

Attached is a patch to move the two files to grub2-common. I intend to
upload this in a few days.

After a week? Sometimes people are busy. Your inference is invalid.

While I acknowledge that this bug is RC, it isn't an emergency and I
don't think you need to do this. I will consider your patch but have
been busy on a project at work that has a deadline of Wednesday, so
please hold off as if this patch is wrong it will be complicated to
unwind properly. I promise I'll look at it ASAP after Wednesday.
