This has been fixed in the debian/experimental with a new algorithm for pinning. I hope that this will be part of Ubuntu 16.04, but it's probably too late and too risky to include in 15.10.

As it was stated by Julian Andres Klode (juliank) in <https://bugs.launchpad.net/ubuntu/+source/apt/+bug/565364/comments/8>: "The pin value displayed after the version does not actually correspond to the version, but is the pin value of the candidate version. This is confusing, yes, we might want to change this in a future release". For example, in <https://bugs.launchpad.net/ubuntu/+source/apt/+bug/565364/comments/7> it was written: mysql-client-5.5: Installed: (none) Candidate: 5.5.31-0ubuntu0.12.04.1 Package pin: 5.5.31-0ubuntu0.12.04.1 Version table: 5.5.31-0ubuntu0.12.04.1 1002 500 http://srv11-msk.msk.mirantis.net/ubuntu-repo/mirror.yandex.ru/ubuntu/ precise-security/main amd64 Packages 500 http://srv11-msk.msk.mirantis.net/ubuntu-repo/mirror.yandex.ru/ubuntu/ precise-updates/main amd64 Packages 5.5.28-23.7ubuntu0.12.04.2+mirantis.wsrep3 1002 1001 http://srv11-msk.msk.mirantis.net/ubuntu-repo/precise-fuel-folsom/ precise-2.1.0.1/main amd64 Packages 5.5.22-0ubuntu1 1002 500 http://srv11-msk.msk.mirantis.net/ubuntu-repo/mirror.yandex.ru/ubuntu/ precise/main amd64 Packages and that 1002 was shown for "5.5.31-0ubuntu0.12.04.1", "5.5.28-23.7ubuntu0.12.04.2+mirantis.wsrep3" and "5.5.22-0ubuntu1 1002"... altough it was related only to "5.5.31-0ubuntu0.12.04.1" (the candidate version). One row should bring particular information about that row, information that is common to all rows should appear in a separate place. I was misleaded, too, by the same kind of problem, and after searching and searching... I found those explanations by Julian Andres Klode and more confused users in <https://bugs.launchpad.net/ubuntu/+source/apt/+bug/565364>. Anyway, thanks for all the good software!
