NAME

       dose-deb-coinstall - calculate a coinstallation set of a given set of Debian binary packages

SYNOPSIS

       dose-deb-coinstall [options] binary-repositories

DESCRIPTION

       dose-deb-coinstall determines whether a set of foreground Debian binary packages can be installed
       together given a set of background Debian binary packages. If a valid coinstallation set exists, than it
       is printed on standard output; else the application exists with exit code 1 and prints nothing.

       If the --src option is given, then the associated source packages are printed on standard output instead.

       Packages are split into foreground and background: only packages in the foreground are checked for
       coinstallability, but dependencies may be satisfied by foreground packages and by background packages. By
       default, all packages are in the foreground.

INPUT FORMAT

       The binary-repositories argument is a list of filenames containing stanzas in the format of
       deb-control(5), separated by one blank line. For instance, the Packages files as found on a Debian mirror
       server, or in the directory /var/lib/apt/lists/ of a Debian system, are suitable.

       The --src option requires a file containing debian source control stanzas, separated by one blank line.
       For instance, the Sources files as found on a Debian mirror server, or in the directory
       /var/lib/apt/lists/ of a Debian system, are suitable.

OPTIONS

       --deb-native-arch=name
               Specify the native architecture. The default behavior is to deduce the native architecture from
               the first package stanza in the input that has an architecture different from all.

       --deb-foreign-archs=name [,name] ...
               Specify a comma-separated list of foreign architectures. The default is an empty list of foreign
               architectures. If --deb-host-arch is set, it is used as an implicit foreign architecture.

       --deb-host-arch=name...
               Specify the host architecture. If this option is given, --deb-native-arch must also be set.

       -f --failures
               Print a diagnostic in YAML format containing the list of packages that were attempted to install
               together and the result of the operation.

       -v --successes
               Only show packages that do not fail the installability check.

       -e --explain
               Explain the results in more detail providing the reason why some packages cannot be installed
               together.

       --src=source-repository
               Instead of printing binary packages, print the associated source packages as given in the debian
               Sources file source-repository.

       --dump=cudf-file
               Dump the CUDF universe to cudf-file representing the encoding of binary and source packages, plus
               the coinstallability request.

       --fg=binary-repository
               Specify a foreground binary repository.

       --bg=binary-repository
               Specify a background binary repository.

       --latest n
               Consider only the latest -n most recent versions of each package, older versions of packages are
               ignored.

       -v      Enable info / warnings / debug messages. This option may be repeated up to three times in order
               to increase verbosity.

       -h, --help
               Display this list of options.

EXIT CODES

       Exit codes 0-63 indicate a normal termination of the program, codes 64-127 indicate abnormal termination
       of the program (such as parse errors, I/O errors).

       In case of normal program termination:

       - exit code 0 indicates that a valid coinstallation set exists

       - exit code 1 indicates that at no coinstallation set exists

EXAMPLE

       Compute the list of binary packages needed to install all packages marked as essential:

        grep-dctrl -X -FEssential yes \
        /var/lib/apt/lists/ftp.fr.debian.org_debian_dists_sid_main_binary-amd64_Packages \
        > essential

        dose-deb-coinstall --deb-native-arch=amd64 \
        --bg /var/lib/apt/lists/ftp.fr.debian.org_debian_dists_sid_main_binary-amd64_Packages \
        --fg essential > essential_coinstall

       Compute the list of source packages needed to build these packages:

        dose-deb-coinstall --deb-native-arch=amd64 \
        --src /var/lib/apt/lists/ftp.fr.debian.org_debian_dists_sid_main_source_Sources \
        --bg /var/lib/apt/lists/ftp.fr.debian.org_debian_dists_sid_main_binary-amd64_Packages \
        --fg essential > essential_coinstall_src
