Package: libitalccore Version: 1:3.0.3+dfsg1-3 Severity: normal Dear Maintainer,
Trying to install the amd64 and i386 versions of this package results in the following error: # apt-get install libitalccore:amd64 libitalccore:i386 [...] Setting up libqt5svg5:i386 (5.10.1-2) ... dpkg: dependency problems prevent configuration of libitalccore:i386: libitalccore:amd64 (1:3.0.3+dfsg1-3) breaks libitalc and is installed. libitalccore:i386 (1:3.0.3+dfsg1-3) provides libitalc. dpkg: error processing package libitalccore:i386 (--configure): dependency problems - leaving unconfigured Processing triggers for libc-bin (2.27-3) ... Errors were encountered while processing: libitalccore:i386 So the source of the issue seems to be that libitalccore: * Provides the libitalc virtual package * Breaks + Replaces the libitalc virtual package Apt seems to consider that this means libitalccore:amd64 breaks libitalccore:i386 through the libitalc virtual package which prevents them from being coinstalled. One strange thing is that, if I understand 7.6.1 of the Debian Policy Manual correctly, Breaks + Replaces is not supposed to be used on virtual packages: http://www.chiark.greenend.org.uk/doc/debian-policy/policy.html/ch-relationships.html#s7.6.1 | For this usage of Replaces, virtual packages (see Virtual packages - Provides, | Section 7.5) are not considered when looking at a Replaces field. The packages | declared as being replaced must be mentioned by their real names. Maybe that's why Apt is confused in this multi-arch configuration. Note that, based on 7.6.2, the usual pattern for virtual packages would be Provides + Conflicts + Replaces: | In this situation, the package declared as being replaced can be a virtual | package, so for example, all mail transport agents (MTAs) would have the | following fields in their control files: | | Provides: mail-transport-agent | Conflicts: mail-transport-agent | Replaces: mail-transport-agent | | ensuring that only one MTA can be unpacked at any one time Seems like something to try to see if it fixes the issue. -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.15.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libitalccore depends on: ii dpkg 1.19.0.5 ii libc6 2.27-3 ii libgcc1 1:8-20180425-1 ii libjpeg62-turbo 1:1.5.2-2+b1 ii libpng16-16 1.6.34-1 ii libqt5core5a 5.10.1+dfsg-5 ii libqt5gui5 5.10.1+dfsg-5 ii libqt5network5 5.10.1+dfsg-5 ii libqt5widgets5 5.10.1+dfsg-5 ii libqt5xml5 5.10.1+dfsg-5 ii libssl1.1 1.1.0h-2 ii libstdc++6 8-20180425-1 ii zlib1g 1:1.2.8.dfsg-5 libitalccore recommends no packages. libitalccore suggests no packages. -- no debconf information
