debsign - sign a Debian .changes and .dsc file pair using GPG
mimics the signing aspects (and bugs) of
. It takes a .dsc
file and signs it, and any child .dsc
, or .changes
files directly or indirectly referenced
by it, using the GNU Privacy Guard. It is careful to calculate the size and
checksums of any newly signed child files and replace the original values in
the parent file.
If no file is specified, debian/changelog
is parsed to determine the name
of the .changes
file to look for in the parent directory.
If a .commands
file is specified it is first validated (see the details
), 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
files to a safe machine and then use the
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
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
machine, then they may be transferred to the remote machine for
signing using debrsign(1)
. However note that it is probably safer to
have your trusted signing machine use debsign
to connect to the
untrusted non-signing machine, rather than using debrsign
to make the
connection in the reverse direction.
This program can take default settings from the devscripts
files, as described below.
- -r [username@]remotehost
- The files to be signed live on the specified remote host. In this case, a
.dsc, .buildinfo or .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:filename 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
- 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
- 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
- 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 current
- --debs-dir DIR
- Look for the files to be signed 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 directory.
- --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
- This specifies the directory in which to look for the files to be signed,
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 the
