NAME
dget - Download Debian source and binary packages
SYNOPSIS
dget [options] URL ...
dget [options] [--all] package[=version] ...
DESCRIPTION
dget downloads Debian packages. In the first form, dget fetches the requested URLs. If this is a .dsc
or .changes file, then dget acts as a source-package aware form of wget: it also fetches any files
referenced in the .dsc/.changes file. The downloaded source is then checked with dscverify and, if
successful, unpacked by dpkg-source.
In the second form, dget downloads a binary package (i.e., a .deb file) from the Debian mirror configured
in /etc/apt/sources.list(.d). Unlike apt-get install -d, it does not require root privileges, writes to
the current directory, and does not download dependencies. If a version number is specified, this
version of the package is requested. With --all, the list of all binaries for the source package package
is extracted from the output of "apt-cache showsrc package".
In both cases dget is capable of getting several packages and/or URLs at once.
(Note that .udeb packages used by debian-installer are located in separate packages files from .deb
packages. In order to use .udebs with dget, you will need to have configured apt to use a packages file
for component/debian-installer).
Before downloading files listed in .dsc and .changes files, and before downloading binary packages, dget
checks to see whether any of these files already exist. If they do, then their md5sums are compared to
avoid downloading them again unnecessarily. dget also looks for matching files in
/var/cache/apt/archives and directories given by the --path option or specified in the configuration
files (see below). Finally, if downloading (.orig).tar.gz or .diff.gz files fails, dget consults apt-get
source --print-uris. Download backends used are curl and wget, looked for in that order.
dget was written to make it easier to retrieve source packages from the web for sponsor uploads. For
checking the package with debdiff, the last binary version is available via dget package, the last source
version via apt-get source package.
OPTIONS
-a, --all
Interpret package as a source package name, and download all binaries as found in the output of "apt-
cache showsrc package". If package is arch-qualified, then only binary packages which are "Arch:
all", "Arch: any", or "Arch: $arch" will be downloaded.
-b, --backup
Move files that would be overwritten to ./backup.
-q, --quiet
Suppress wget/curl non-error output.
-d, --download-only
Do not run dpkg-source -x on the downloaded source package. This can only be used with the first
method of calling dget.
-x, --extract
Run dpkg-source -x on the downloaded source package to unpack it. This option is the default and can
only be used with the first method of calling dget.
-u, --allow-unauthenticated
Do not attempt to verify the integrity of downloaded source packages using dscverify.
--build
Run dpkg-buildpackage -b -uc on the downloaded source package.
--path DIR[:DIR ...]
In addition to /var/cache/apt/archives, dget uses the colon-separated list given as argument to
--path to find files with a matching md5sum. For example: "--path
/srv/pbuilder/result:/home/cb/UploadQueue". If DIR is empty (i.e., "--path ''" is specified), then
any previously listed directories or directories specified in the configuration files will be
ignored. This option may be specified multiple times, and all of the directories listed will be
searched; hence, the above example could have been written as: "--path /srv/pbuilder/result --path
/home/cb/UploadQueue".
-k, --insecure
Allow SSL connections to untrusted hosts.
--no-cache
Bypass server-side HTTP caches by sending a Pragma: no-cache header.
-h, --help
Show a help message.
-V, --version
Show version information.
CONFIGURATION VARIABLES
The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced by a shell in that order
to set configuration variables. Command line options can be used to override configuration file
settings. Environment variable settings are ignored for this purpose. The currently recognised variable
is:
DGET_PATH
This can be set to a colon-separated list of directories in which to search for files in addition to
the default /var/cache/apt/archives. It has the same effect as the --path command line option. It
is not set by default.
DGET_UNPACK
Set to 'no' to disable extracting downloaded source packages. Default is 'yes'.
DGET_VERIFY
Set to 'no' to disable checking signatures of downloaded source packages. Default is 'yes'.
EXAMPLES
Download all .deb files for the previous version of a package and run debdiff on them:
dget --all mypackage=1.2-1
debdiff --from *_1.2-1_*.deb --to *_1.2-2_*.deb
BUGS AND COMPATIBILITY
dget package should be implemented in apt-get install -d.
Before devscripts version 2.10.17, the default was not to extract the downloaded source. Set
DGET_UNPACK=no to revert to the old behaviour.
