Package: apt Version: 1.8.2.1 Severity: normal Dear Maintainer,
When I apt install --simulate docker.io/unstable, apt picks needrestart 3.5-1 to meet a dependency, even though it has a lower pin priority than 3.4-5 and no package (not even docker/unstable) requires a version newer than 3.1~ . This surprises me. Is it a bug? $ apt install --simulate -o debug::pkgProblemResolver=1 docker.io/unstable NOTE: This is only a simulation! apt needs root privileges for real execution. Keep also in mind that locking is deactivated, so don't depend on the relevance to the real current situation! Reading package lists... Done Building dependency tree Reading state information...

But why did it pick the version with a lower pin priority? The docker.io package should be happy with the older, stable, higher-priority version: $ apt depends docker.io/unstable |grep needrestart Recommends: needrestart (>= 3.1~) Does apt actually see my pin priorities? Yep: $ apt policy needrestart needrestart: Installed: (none) Candidate: 3.4-5 Version table: 3.5-1 100 100 http://deb.debian.org/debian unstable/main arm64 Packages 3.4-5 500 500 http://deb.debian.org/debian buster/main arm64 Packages Are my pin priorities correct? I think so: $ cat /etc/apt/preferences.d/*pref Package: linux-image-* linux-headers-* Pin: release a=unstable Pin-Priority: 500 Package: * Pin: release a=unstable Pin-Priority: 100 Perhaps some other package requires a newer version of needrestart? Nope: $ apt rdepends needrestart needrestart Reverse Depends: Recommends: docker.io (>= 3.1~) Suggests: unattended-upgrades Depends: freedombox Depends: needrestart-session (>= 2.0) Recommends: docker.io (>= 3.1~) Depends: parl-desktop Depends: design-desktop Suggests: aptitude-robot Recommends: apt-dater-host Suggests: unattended-upgrades Depends: needrestart-session (>= 2.0) Recommends: apt-dater-host Depends: parl-desktop Depends: design-desktop Suggests: aptitude-robot I realize that apt has been around for quite a while, so I'm reluctant to assume that I've stumbled upon a bug, but I don't understand this behavior. I had a nice chat with someone on #debian-apt who didn't understand it either. If this is expected, perhaps someone familiar with apt internals can explain?
