> This is a feature, so you can pin a release (like backports) to a low value, but raise it easily if you need to.
I know, except in this case it actually _lowers_ the value. > It is also explicitly documented in the apt_preferences manpage, which also mentions a "workaround": Note that this [= the target release setting] has precedence over any general priority you set in the /etc/apt/preferences file described later, but not over specifically pinned packages. Ok, but specifically naming all packages I want to pin is very inconvenient if I want it to apply to all packages in that PPA. It seems to me you simply dismissed my report without trying to understand my use case. If this is indeed "a feature", imho it's problematic and should be discussed. Is there any good reason why the target release setting should lower the priority of a package? The intuitive thing would be that the priority never gets set below the manually specified value. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1565782 Title: APT doesn't respect pin-priority when using APT::Default-Release option Status in apt package in Ubuntu: Invalid Bug description: I'm trying to pin packages from the proprietary graphics drivers PPA, and I want APT to use this PPA even if a newer version is available in a target release, so I put it at a pin-priority of 999 --- /etc/apt/preferences.d/graphics-drivers-ppa-pin-999 Package: * Pin: release o=LP-PPA-graphics-drivers Pin-Priority: 999 --- If I test this with 'apt-cache policy', the priorities seems to be correct. --- $ apt-cache policy nvidia-346 nvidia-346: Installerad: 346.96-0ubuntu0~gpu14.04.2 Kandidat: 346.96-0ubuntu0~gpu14.04.2 Versionstabell: 352.63-0ubuntu0.14.04.1 0 500 http://se.archive.ubuntu.com/ubuntu/ trusty-updates/restricted amd64 Packages 500 http://security.ubuntu.com/ubuntu/ trusty-security/restricted amd64 Packages *** 346.96-0ubuntu0~gpu14.04.2 0 999 http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status --- But if I use the 'APT::Default-Release' configuration option, the priority gets lowered to 990, resulting in the wrong candidate. --- $ apt-cache -o 'APT::Default-Release=trusty' policy nvidia-346 nvidia-346: Installerad: 346.96-0ubuntu0~gpu14.04.2 Kandidat: 352.63-0ubuntu0.14.04.1 Versionstabell: 352.63-0ubuntu0.14.04.1 0 990 http://se.archive.ubuntu.com/ubuntu/ trusty-updates/restricted amd64 Packages 990 http://security.ubuntu.com/ubuntu/ trusty-security/restricted amd64 Packages *** 346.96-0ubuntu0~gpu14.04.2 0 990 http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status --- The same thing happens when using apt-get/aptitude's '-t' flag, i.e. the wrong version gets marked for installation. It seems the policy engine sets the priority to 990 if the package matches the target release, regardless of the previous (higher) value. I think this behavior is a bug and should be fixed so that a certain package's priority doesn't get lowered for belonging to the target release.
