dget -- Download Debian source and binary packages
dget downloads Debian packages. In the first form, dget fetches the requested URL. 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 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.
(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.
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 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.
