PROGRAM:

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.

-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
