Package: apt Version: 2.5.1 Severity: normal Dear Maintainer,
I noticed that the ?archive pattern does not behave the same in apt as in aptitude. My system has both unstable and experimental suites enabled (see below debian.sources). When I run: aptitude versions '~i~Aexperimental' I get a list of those installed package versions that effectively come from experimental (8 in total on my system, in particular I use GCC 12 by default): Package cpp: i A 4:12-20211211-1 experimental 100 Package g++: i 4:12-20211211-1 experimental 100 … However, when I run: apt list '~i~Aexperimental' I get a list of 297 packages. It seems to include all the installed packages for which a more recent version exists in experimental, independently of whether I installed that more recent version or not. For example, the output contains: wfrench/unstable,now 1.2.6-1 all [installed,automatic] wfrench 1.2.6-1 actually comes from unstable, but there is indeed a 1.2.7-1 currently in experimental (which I did not install). This behaviour seems to contradict the documentation, so I guess it is not intended (or the documentation should probably be clarified otherwise, and this be added to the incompatibilites with aptitude). Thanks for your work, Sébastien Villemot -- Package-specific info: -- (no /etc/apt/preferences present) -- -- (no /etc/apt/preferences.d/* present) -- -- (no /etc/apt/sources.list present) -- -- /etc/apt/sources.list.d/debian.sources -- Types: deb deb-src URIs: http://deb.debian.org/debian Suites: unstable experimental Components: main contrib non-free Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.18.0-2-amd64 (SMP w/16 CPU threads; PREEMPT) Locale: LANG=fr_FR.utf8, LC_CTYPE=fr_FR.utf8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages apt depends on: ii adduser 3.122 ii debian-archive-keyring 2021.1.1 ii gpgv 2.2.35-3 ii libapt-pkg6.0 2.5.1 ii libc6 2.33-8 ii libgcc-s1 12.1.0-7 ii libgnutls30 3.7.6-2 ii libseccomp2 2.5.4-1 ii libstdc++6 12.1.0-7 ii libsystemd0 251.3-1 Versions of packages apt recommends: ii ca-certificates 20211016 Versions of packages apt suggests: ii apt-doc 2.5.1 ii aptitude 0.8.13-4 ii dpkg-dev 1.21.9 ii gnupg 2.2.35-3 ii gnupg2 2.2.35-3 ii powermgmt-base 1.36 ii synaptic 0.91.2 -- no debconf information
