Virtual dependency satisfaction picks the first possible provider alphabetically (bug 473247), but doesn't consider whether a package that will be installed later in this same run will satisfy the dependency. To give a concrete example, consider xdg-utils (Depends: iceweasel | www-browser) and firefox (Depends: firefox-3.5 which provides www-browser). Depending on how you order your apt-get line, you may end up with the arora browser. To reproduce, in a chroot without any www-browsers installed: $ apt-get install -s xdg-utils firefox | grep arora $ apt-get install -s firefox xdg-utils | grep arora The first line will install arora (i.e. give output). The second line will not install arora and will give no output. I claim that the set of installed packages should be the same (possibly with different install order, but the same set of packages). Though maybe I'm misunderstanding how apt-get is designed to work when I expect that. -- Package-specific info: -- (no /etc/apt/preferences present) -- -- (/etc/apt/sources.list present, but not submitted) -- -- System Information: Debian Release: squeeze/sid APT prefers karmic-updates APT policy: (500, 'karmic-updates'), (500, 'karmic-security'), (500, 'karmic') Architecture: i386 (i686) Kernel: Linux 2.6.31-15-generic (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages apt depends on: ii libc6 2.10.1-0ubuntu15 GNU C Library: Shared libraries ii libgcc1 1:4.4.1-4ubuntu8 GCC support library ii libstdc++6 4.4.1-4ubuntu8 The GNU Standard C++ Library v3 Versions of packages apt recommends: ii ubuntu-keyring 2009.08.28 GnuPG keys of the Ubuntu archive Versions of packages apt suggests: pn apt-doc <none> (no description available) ii aptitude 0.4.11.11-1ubuntu6 terminal-based package manager ii bzip2 1.0.5-3 high-quality block-sorting file co ii dpkg-dev 1.15.4ubuntu2 Debian package development tools ii lzma 4.43-14ubuntu1 Compression method of 7z format in ii python-apt 0.7.13.2ubuntu4 Python interface to libapt-pkg ii synaptic 0.62.7ubuntu6 Graphical package manager -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
