I have moved to stretch-backports as many packages as I could (I have to see what I do with the few, ~5, remaining). Regards! Felix

If you actually *build* packages from "stable" on "testing" system, using dependencies for building also from "testing" then it should be ok compatibility wise.

I haven't seen any particular issues so far, only problems I had were _before_ the upgrade when I had to purge a few packages and libraries from the old "debian-multimedia" repo... after that, the upgrade to testing went well and not a problem since.

How can I prevent this downgrading from happening? here are magic levels for the numbers in the priority field. They are explained, at length, in man apt_preferences. The highlights: P >= 1000 causes a version to be installed even if this constitutes a downgrade of the package 990 <= P < 1000 causes a version to be installed even if it does not come from the target release, unless the installed version is more recent 500 <= P < 990 causes a version to be installed unless there is a version available belonging to the target release or the installed version is more recent 100 <= P < 500 causes a version to be installed unless there is a version available belonging to some other distribution or the installed version is more recent 0 < P < 100 causes a version to be installed only if there is no installed version of the package P < 0 prevents the version from being installed Your downgrades are probably caused by the 1001 priority for stable; changing that to 999 might be what you want. -dsr-

[1] The right and safe way to run stable branch and install packages from other branches (eg testing) is to make backports of them. [2] This is why debian-backports branch exists. When doing it right way you won't need any pinning and if package you backported will hit stretch-backports branch and will be newer version it will be upgraded just as regular package.

prevent apt from downgrading packages
Hi all, I have mix stable+testing (~1200 packages from stable, ~20 packages from testing). I have the following contents in /etc/apt/preferences.d/pinning: Package: * Pin: release a=stable Pin-Priority: 1001 Package: * Pin: release a=testing Pin-Priority: 200 Package: * Pin: release a=experimental Pin-Priority: -10 Package: * Pin: release a=unstable Pin-Priority: -10 What happens is: after an apt update, I list the packages to be upgraded with apt list --upgradable, and I get only those that will be upgraded. However, when I run apt upgrade, I get a number of packages that will be downgraded. How can I prevent this downgrading from happening? Thank you! Felix
