Package: apt
Version: 0.9.3
Severity: normal
Dear Maintainers,
It seems that the "install-recommended" option will treat recommended exactly
like "depends". However in some cases this is not the desired behavior. For
example, you would not want a recommended package's installation to force
the uninstall of an already-installed package.
I have installed a metapackage called snl-workstation which conflicts with
nvidia-kernel-common. When I install or upgrade the package libcuda1, it
recommends nvidia-kernel-295.49 which ultimately depends on
nvidia-kernel-common.
`apt-get install snl-workstation libcuda1` has the correct outcome:
snl-workstation is installed and libcuda1's incompatible recommends are
ignored.
However `apt-get install snl-workstation; apt-get install libcuda1` will remove
snl-workstation in order to install nvidia-kernel-common because libcuda1's
recommends are treated as depends.
I think this is a bug. A recommend should never be installed if it conflicts
with a currently installed package.
A workaround is `apt-get install --no-install-recommends libcuda1`, but
this is not ideal. I still want recommends installed, just not conflicting
recommends.
Thanks,
Chris

This is not a bug. The debian-policy says:
"The Recommends field should list packages that would be found together
with this one in all but unusual installations."
Ignoring a recommends therefore means your system becomes unusual -
something a user should decide for itself and not the package manager
in it's default behavior. Hence the need for tweaking the result.
Beside, the situation is a tat more complex than you described:
libcuda1 -> recommends: nvidia-kernel-295.49 ->
provided by: nvidia-kernel-dkms -> depends: nvidia-kernel-common
I don't know what your snl-workstation includes or for what do you need
libcuda1, but i guess snl-workstation includes an nvidia kernel module
or at least a way to build it.
If so, feel free to provide nvidia-kernel-295.49 in snl-workstation and
your problem is solved - in a clean and nice way for all sorts of
dependencies on nvidia-kernel-295.49 …
Best regards
David Kalnischkies
