dget - Download Debian source and binary packages
-
dget [options] URL ...
-
dget [options] [--all]
package[=version] ...
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.
-
-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.
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'.
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
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.
