dscverify - verify the validity of a Debian package


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


dscverify checks that the GPG 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.


--keyring keyring
Add keyring to the list of keyrings to be used.

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.

Do not suppress GPG output.

--help, -h
Display a help message and exit successfully.

Display version and copyright information and exit successfully.


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:

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


Please note that the keyring provided by the debian-keyring package can be slightly out of
date.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'


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

- ~/.gnupg/trustedkeys.gpg

- /org/keyring.debian.org/keyrings/debian-keyring.gpg

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

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