Package: aptitude Version: 0.4.1-1 Severity: important I am tagging this as important because any bug that makes people install experimental packages unawares is quite problematic :)
$ apt-cache policy libarts1c2a libarts1c2a: Installed: 1.4.3-3 Candidate: 1.5.0-3 Version table: 1.5.0-3 0 990 http://mirrors.kernel.org unstable/main Packages 990 http://ftp.fi.debian.org unstable/main Packages 1.5.0-2 0 -10 http://mirrors.kernel.org experimental/main Packages -10 http://ftp.fi.debian.org experimental/main Packages *** 1.4.3-3 0 100 /var/lib/dpkg/status However, aptitude does this: libarts1c2a recommends libarts1-akode --\ The following actions will resolve this dependency: -> Upgrade libarts1c2a [1.4.3-3 (now) -> 1.5.0-2 (experimental, experimental)] -> Keep libarts1c2a at version 1.4.3-3 (now) -> Remove libarts1c2a [1.4.3-3 (now)] -> Install libarts1-akode [4:3.5.0-2 (experimental, experimental)] -> Leave the dependency "libarts1c2a recommends libarts1-akode" unresolved. i.e it prefers to install the experimental version, even if it is priority -10. The correct solution is to install libarts1c2a 1.5.0-3, and leave the dependency unresolved. OR to hold everything. But installing anything that has a negative priority is a no-no.
