This means that if you access the depcache, it does not respect pinning when calculating upgrades. This is not a general problem - according to current knowledge, it only affects apt list. It does affect any code that requests a depCache from pkgCacheFile without having explicitly build caches, or explicitly initialized policy (which other parts of apt do). [Test case] 1. Add deb https://esm.ubuntu.com/ubuntu/ trusty-infra-security main to sources.list 2. Pin it down Package: * Pin: release trusty-infra-security Pin-Priority: -1 3. Look at apt list apport Currently it shows: apport/trusty-updates,trusty-security,now 2.14.1-0ubuntu3.29 all [installed,upgradable to: 2.14.1-0ubuntu3.29] because when calculating whether the package is upgradable, it did not see the pinning. Correct would be: apport/trusty-updates,trusty-security,now 2.14.1-0ubuntu3.29 all [installed] [Regression potential] Behavior of code that only initializes depcache, but not policy will change. For example, pinning will be applied in such code (as it is in later versions, and should be). This adds some more error cases as well, such as parsing failures for preferences files.
