Package: python-apt Version: 0.9.3.6 Severity: normal Dear Maintainer,
python-apt fails to find installed packages of different architecture when reading metadata from a deb file. For example, I've installed libopenjpeg5:i386 on an amd64 system: ``` $ apt-cache policy libopenjpeg5:i386 libopenjpeg5:i386: Installed: 1.5.2-2 Candidate: 1.5.2-2 Version table: *** 1.5.2-2 0 500 http://ftp.cn.debian.org/debian/ unstable/main i386 Packages 100 /var/lib/dpkg/status limbo@Skypiea in ~/.vim/bundle/YouCompleteMe [master] $ apt-cache policy libopenjpeg5 libopenjpeg5: Installed: (none) Candidate: 1.5.2-2 Version table: 1.5.2-2 0 500 http://ftp.cn.debian.org/debian/ unstable/main amd64 Packages ``` But when I use python-apt to read the deb file, it reports that this package is NOT installed on my system: ```python from apt.debfile import DebPackage pkg = DebPackage('/var/cache/apt/archives/libopenjpeg5_1.5.2-2_i386.deb') print pkg.compare_to_version_in_cache() == DebPackage.VERSION_SAME # => False print pkg.compare_to_version_in_cache() == DebPackage.VERSION_NONE # => True ``` I think the problem resides in function `compare_to_version_in_cache()` in `debfile.py`, which does not check package names appended with architecture name suffix. -- System Information: Debian Release: jessie/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.12.14-debian (SMP w/4 CPU cores; PREEMPT) 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 python-apt depends on: ii libapt-inst1.5 1.0.3 ii libapt-pkg4.12 1.0.3 ii libc6 2.18-7 ii libgcc1 1:4.9.0-5 ii libstdc++6 4.9.0-5 ii python 2.7.6-2 ii python-apt-common 0.9.3.6 Versions of packages python-apt recommends: ii iso-codes 3.53-1 ii lsb-release 4.1+Debian12 ii xz-utils 5.1.1alpha+20120614-2 Versions of packages python-apt suggests: pn python-apt-dbg <none> pn python-apt-doc <none> ii python-gtk2 2.24.0-3+b1 ii python-vte 1:0.28.2-5 -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
