Package: apt
Version: 0.9.7.9+deb7u6
Severity: important

Dear maintainer,

I added Jessie as a installation source at lower priority to my wheezy
server VM. It seems owncloud seems to be removed from testing[1]. To have
updated owncloud packages with all security fixes, I can either go for
upstream packages or to testing packages. I decided for the later
according to a recommendation[2].

In order to not have every package in wheezy-backports upgraded to testing
I made sure that wheezy-backports is pinned above testing.

That way there should not be any upgrades to the system unless I explicitely
ask for them. And aptitude agrees:

mondschein:~> LANG=C aptitude dist-upgrade
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.

Yet apt-get insists otherwise:

mondschein:~> LANG=C apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

mondschein:~> LANG=C apt-get dist-upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
The following NEW packages will be installed:
  libaudit0 libcryptsetup4 libpam-systemd libsystemd-daemon0
  libsystemd-id128-0 libsystemd-journal0 libsystemd-login0 systemd
0 upgraded, 8 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B/1765 kB of archives.
After this operation, 4573 kB of additional disk space will be used.
Do you want to continue [Y/n]? n
Abort.


This seems to be broke for me in two ways:

1) On the apt upgrade those systemd packages are not shown as held back.

2) It has no business to install these anyway. None of the packages is
currently installed and surely wheezy is priority 500 and testing is priority
150. So no business to install these. Even when I lower testing priority to 100
it insists to install these.

So it only installs *new* packages, without any existing packages depending
on them - so it appears to me.

I think it has no business to install these, and while I see that
systemd-sysv would not be installed, I´d rather keep my wheezy system
systemd free until I properly switch to it during upgrade to jessie. As
I do not like to run systemd packages on a mixture of wheezy and testing
which in itself is a work-around due to the owncloud package being
removed from testing.

I even did the install of these systemd related packages and purged them
again without any issue. So there is really *nothing* depending on it.
Why does it install these? Maybe due to being marked as essential? If so,
is there a way to tell apt not to install any essential packages from a
distro version that is not the default release?

It has "business". At least it believes it has, while aptitude has
decided to ignore this case. You can proof that both is a bad idea in
certain cases, so it ends up to be a design decision:

Jessie introduces a new essential package ("init") and a key concept of
essential packages is that other packages do not need to depend on it,
even if they need it, which means that as soon as you add jessie
sources, apt will try to install this init package (and its
dependencies) to ensure that you are not breaking your system while you
install (other) packages from jessie (it does so only in d-u as this is
used for dist(ribution)-upgrades and new essential appear only with new
releases, not in between. Also, upgrade wouldn't be allowed to install
a new package anyway).

Also, your description of 2) suggests that you have slightly
misunderstood pinning, so the apt_preferences manpage might be a good
read. I would guess a pin value below 100 is more what you want.

Of note is also my bugreport #760458 which if implemented would solve
your precieved problem, but it seems like it was decided against it.

As there is nothing we can do about it as it is declared "feature"
rather than bug, I am closing this report, but still thanks for the
report (– and I hope my reasoning makes at least a bit of sense, if not
feel free to ask).

Best regards

David Kalnischkies
