debian-keyring 2018.03.24 (arm64 binary) in ubuntu bionic

 The Debian project wants developers to digitally sign the
 announcements of their packages with GnuPG, to protect against
 forgeries. This package contains keyrings of GnuPG and keys of
 Debian Developers (uploading and non-uploading), as well as of Debian
 Maintainers.
 .
 Do note that, although this package is provided for convenience, it
 is not necessarily kept updated with the latest changes; the authoritative
 source for keyring information is publicly accessible via rsync at:
 .
 keyring.debian.org::keyrings/keyrings/
 .
 Finally, the following Git repository is usually kept up to date with the
 public authoritative data:
