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
