Package: apt
Version: 1.0.10.2
Severity: important

Dear Maintainer,

   * What led up to the situation?
I am currently running debian testing and I tried installing digikam. This is one of the packages infect by the libstdc++6 issue, I know of that issue, but I believe to have stumbled into an apt-get bug.

I tried installing the stable version, but apt-get won't install it as the dependencies are not met:

$ sudo apt-get install digikam-private-libs/jessie
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Selected version '4:4.4.0-1.1' (Debian:8.2/stable [amd64]) for 'digikam-private-libs'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 digikam-private-libs : Depends: libbaloofiles4 (>= 4:4.12.80) but it is not going to be installed
                        Depends: libkdcraw23 (>= 4:4.12.3) but it is not going to be installed

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

Most notable the third-last line:
 libstdc++6 : Breaks: digikam-private-libs (<= 4:4.4.0-1.1+b2) but 4:4.4.0-1.1 is to be installed

If I understand correctly, "4:4.4.0-1.1" <= "4:4.4.0-1.1+b2" but apt-get does not seem to agree with me.

You can check if you agree with the Debian way of interpreting versions
e.g. with:

$ dpkg --compare-versions '4:4.4.0-1.1' '<=' '4:4.4.0-1.1+b2'
$ echo $?
0

So returncode of this command is indeed 0 aka dpkg and you agree – and
apt agrees as well (as it is basically using the same code as dpkg) BUT
we are talking about a "Breaks" relation here, not a "Depends" as all
the others are:
"Breaks", like "Conflicts", indicate that two packages do not play
nicely together, so as long as the given Breaks clause it satisfied,
the package isn't installable. So, you actually want to have Breaks
not satisfied, but in your example it is.

So, given that we all agree on the interpretation of the version I am
going to close this bug as a misunderstanding of package relations, but
feel free to reopen if I ended up misunderstanding you.

Best regards

David Kalnischkies
