DSCVERIFY(1)

NAME

dscverify - verify the validity of a Debian package

SYNOPSIS

dscverify [--keyring keyring] ... changes_or_dsc_filename ...

DESCRIPTION

dscverify checks that the GPG or PGP signatures on the given .changes or .dsc files are good signatures made by keys in the current Debian keyrings, found in the debian-keyring and debian-maintainers packages. (Additional keyrings can be specified using the --keyring option any number of times.) It then checks that the other files listed in the .changes or .dsc files have the correct sizes and checksums (MD5 plus SHA1 and SHA256 if the latter are present). The exit status is 0 if there are no problems and non-zero otherwise.

OPTIONS

--keyring keyring
Add keyring to the list of keyrings to be used.
--no-default-keyrings
Do not use the default set of keyrings.
--no-conf, --noconf
Do not read any configuration files. This can only be used as the first option given on the command-line.
--nosigcheck, --no-sig-check, -u
Skip the signature verification step. That is, only verify the sizes and checksums of the files listed in the .changes or .dsc files.
--verbose
Do not suppress GPG output.
--help, -h
Display a help message and exit successfully.
--version
Display version and copyright information and exit successfully.

CONFIGURATION VARIABLES

The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced by a shell in that order to set configuration variables. Environment variable settings are ignored
for this purpose. If the first command line option given is
--noconf or --no-conf, then these files will not be read. The currently recognised variable is:

DSCVERIFY_KEYRINGS
This is a colon-separated list of extra keyrings to use
in addition to any specified on the command line.

KEYRING

Please note that the keyring provided by the debian-keyring
package can be slightly out of date. The latest version can be
obtained with rsync, as documented in the README that comes with
debian-keyring. If you sync the keyring to a non-standard location (see below), you can use the possibilities to specify extra
keyrings, by either using the above mentioned configuration
option or the --keyring option.

Below is an example for an alias:

alias dscverify='dscverify --keyring ~/.gnupg/pubring.gpg'

STANDARD KEYRING LOCATIONS

By default dscverify searches for the debian-keyring in the following locations:

- /org/keyring.debian.org/keyrings/debian-keyring.(gpg|pgp)

- /usr/share/keyrings/debian-keyring.(pgp|gpg)

- /usr/share/keyrings/debian-maintainers.gpg

SEE ALSO

gpg(1) and devscripts.conf(5).
