Package: dpkg Version: 1.18.7 Severity: serious Justification: Prevents the installation of a packages/leaves package in a broken state.
Hi, Installing a new version of the package imagemagick is failing: #dpkg -i /var/cache/apt/archives/imagemagick_8%3a6.9.2.10+dfsg-2_all.deb (Reading database ... 431189 files and directories currently installed.) Preparing to unpack .../imagemagick_8%3a6.9.2.10+dfsg-2_all.deb ... dpkg-query: no packages found matching imagemagick:all dpkg-query: package 'imagemagick' is not installed Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. dpkg-query: package 'imagemagick' is not installed Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. dpkg-query: package 'imagemagick' is not installed Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. dpkg-query: package 'imagemagick' is not installed Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. dpkg-query: package 'imagemagick' is not installed Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. dpkg-maintscript-helper: error: directory '/usr/share/doc/imagemagick' contains files not owned by package imagemagick:all, cannot switch to symlink dpkg: error processing archive /var/cache/apt/archives/imagemagick_8%3a6.9.2.10+dfsg-2_all.deb (--install): subprocess new pre-installation script returned error exit status 1 Errors were encountered while processing: /var/cache/apt/archives/imagemagick_8%3a6.9.2.10+dfsg-2_all.deb The current status of the package imagemagick from dpkg -l is: ii imagemagick 8:6.9.1.2-1 amd64 image manipulation programs -- binaries The problematic output appears to be coming from dpkg-maintscript-helper, invoked with the following dpkg environment variables, and command line: DPKG_ROOT= DPKG_MAINTSCRIPT_DEBUG=1 DPKG_MAINTSCRIPT_ARCH=all DPKG_RUNNING _VERSION=1.18.7 DPKG_MAINTSCRIPT_NAME=preinst DPKG_MAINTSCRIPT_PACKAGE=im agemagick DPKG_ADMINDIR=/var/lib/dpkg #dpkg-maintscript-helper dir_to_symlink /usr/share/doc/imagemagick /usr/share/doc/imagemagick-6-common 8:6.9.2.10+dfsg-2~ -- upgrade 8:6.9.1.2-1 8:6.9.2.10+dfsg-2 The problem seems to be that dpkg-maintscript-helper is expecting that the already installed version is of the same architecture as given in DPKG_MAINTSCRIPT_ARCH. It is unclear to me if this is a deficiency of dpkg-maintscript-helper or the caller. Thanks, Matthew W.S. Bell
