debsign - sign a Debian .changes and .dsc file pair using GPG
mimics the signing aspects (and bugs) of
(1). It takes either an unsigned .dsc
file or an unsigned .changes
file (along with the associated
file found by replacing the architecture name and
if it appears in the .changes
file), and signs them using the GNU Privacy Guard. It is
careful to calculate the size and checksums of the newly signed
file and replace the original values in the .changes
If a .changes, .dsc or .commands file is specified,
it is signed, otherwise, debian/changelog is parsed to determine
the name of the .changes file to look for in the parent
If a .commands file is specified it is first validated (see the
details at ftp://ftp.upload.debian.org/pub/UploadQueue/README),
and the name specified in the Uploader field is used for signing.
This utility is useful if a developer must build a package on one
machine where it is unsafe to sign it; they need then only transfer
the small .dsc and .changes files to a safe machine and
then use the debsign program to sign them before
transferring them back. This process can be automated in two ways.
If the files to be signed live on the remote machine, the -r
option may be used to copy them to the local machine and back again
after signing. If the files live on the local machine, then they may
be transferred to the remote machine for signing using
This program can take default settings from the devscripts
configuration files, as described below.
- -r [username@]remotehost
The .changes and .dsc files live on the specified remote
host. In this case, a .changes file must be explicitly named,
with an absolute directory or one relative to the remote home
directory. scp will be used for the copying. The
[username@]remotehost:changes syntax is
permitted as an alternative. Wildcards (* etc.) are allowed.
When debsign needs to execute GPG to sign it will run progname
(searching the PATH if necessary), instead of gpg.
Specify the maintainer name to be used for signing. (See
dpkg-buildpackage(1) for more information about the differences
between -m, -e and -k when building packages;
debsign makes no use of these distinctions except with respect
to the precedence of the various options. These multiple options are
provided so that the program will behave as expected when called by
Same as -m but takes precedence over it.
Specify the key ID to be used for signing; overrides any -m
and -e options.
Look for a source-only .changes file instead of a binary-build
- -adebian-architecture, -tGNU-system-type
See dpkg-architecture(1) for a description of these options.
They affect the search for the .changes file. They are provided
to mimic the behaviour of dpkg-buildpackage when determining the
name of the .changes file.
Multiarch .changes mode: This signifies that debsign should
use the most recent file with the name pattern
package_version_*+*.changes as the .changes file, allowing for the
.changes files produced by dpkg-cross.
- --re-sign, --no-re-sign
Recreate signature, respectively use the existing signature, if the
file has been signed already. If neither option is given and an already
signed file is found the user is asked if he or she likes to use the
- --debs-dir DIR
Look for the .changes and .dsc files in directory
DIR instead of the parent of the source directory. This should
either be an absolute path or relative to the top of the source
- --no-conf, --noconf
Do not read any configuration files. This can only be used as the
first option given on the command-line.
- --help, -h
Display a help message and exit successfully.
Display version and copyright information and exit successfully.
The two configuration files /etc/devscripts.conf
are sourced 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 variables are:
Setting this is equivalent to giving a -p option.
This is the -m option.
And this is the -k option.
Always re-sign files even if they are already signed, without prompting.
This specifies the directory in which to look for the .changes
and .dsc files, and is either an absolute path or relative to
the top of the source tree. This corresponds to the
--debs-dir command line option. This directive could be
used, for example, if you always use pbuilder or
svn-buildpackage to build your packages. Note that it also
affects debrelease(1) in the same way, hence the strange name of
