Hi, just for the archive:
I think i found the source code which emits the "[...]" strings of apt-list: https://sources.debian.org/src/apt/2.9.4/apt-private/private-output.cc/#L292 The possible status strings are: [installed,upgradable to: ...] [installed,local] [installed,auto-removable] [installed,automatic] [installed] [upgradable from: ...]" [residual-config] More seem not to exist. Their meaning has to be guessed from the names of methods, variables, and constants in the code. (I believe "pkgCache::Flag::Auto" is a constant and not an overloaded monster car. With C++ one never knows what's behind a name.) if (P->CurrentVer != 0) { if (P.CurrentVer() == V) { if (state.Upgradable() && state.CandidateVer != NULL) strprintf(StatusStr, _("[installed,upgradable to: %s]"), else if (V.Downloadable() == false) StatusStr = _("[installed,local]"); else if(V.Automatic() == true && state.Garbage == true) StatusStr = _("[installed,auto-removable]"); else if ((state.Flags & pkgCache::Flag::Auto) == pkgCache::Flag::Auto) StatusStr = _("[installed,automatic]"); else StatusStr = _("[installed]"); } else if (state.CandidateVer == V && state.Upgradable()) strprintf(StatusStr, _("[upgradable from: %s]"), InstalledVerStr.c_str()); } else if (V.ParentPkg()->CurrentState == pkgCache::State::ConfigFiles) StatusStr = _("[residual-config]"); --------------------------------------------------------------------- About my post-upgrade activities: I ran the command that is proposed in https://www.debian.org/releases/stable/amd64/release-notes/ch-upgrading.en.html#purge-removed-packages apt purge '~c' It flooded me with package names under the headline The following packages were automatically installed and are no longer required: ... Use 'apt autoremove' to remove them. Then it offered me a list with slightly frightening wildcards: The following packages will be REMOVED: fuse* libreoffice-avmedia-backend-gstreamer* linux-image-4.19.0-17-amd64* linux-image-4.19.0-20-amd64* linux-image-4.19.0-9-amd64* python* python-twisted-core* wicd-daemon* wicd-gtk* After my confirmation it purged the 9 configurations which were reported by "apt list '~c'" Purging configuration files for fuse (2.9.9-5) ... ... Purging configuration files for python (2.7.16-1) ... and as last line said Processing triggers for dbus (1.14.10-1~deb12u1) ... Somewhat mistrusting about the removal of "python" i asked apt-file from where my current /usr/bin/python stems. Answer: python-is-python3 . (As side result i now wonder how the result of /usr/bin/python3-pasteurize might taste and how long it stays fresh.) I will probably run "apt autoremove" after verifying that the few worthy local packages are not in the list proposed for autoremoval. Have a nice day :) Thomas
