dget -- Download Debian source and binary packages
- dget [options] URL ...
- dget [options] [--all]
downloads Debian packages. In the first form, dget
the requested URLs. If this is a .dsc or .changes file, then dget
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
and, if successful, unpacked by dpkg-source
In the second form, dget
downloads a binary
package (i.e., a
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
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

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
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

was written to make it easier to retrieve source packages from the
web for sponsor uploads. For checking the package with debdiff

source version via apt-get source package
- -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
- -u, --allow-unauthenticated
- Do not attempt to verify the integrity of downloaded source packages using
- 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
- Allow SSL connections to untrusted hosts.
- Bypass server-side HTTP caches by sending a Pragma: no-cache
- -h, --help
- Show a help message.
- -V, --version
- Show version information.
The two configuration files /etc/devscripts.conf
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
- 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.
- Set to 'no' to disable extracting downloaded source packages. Default is
- Set to 'no' to disable checking signatures of downloaded source packages.
Default is 'yes'.
Download all .deb
files for the previous version of a package and run
dget --all mypackage=1.2-1
debdiff --from *_1.2-1_*.deb --to *_1.2-2_*.deb
BUGS AND COMPATIBILITY¶
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.
