Hi, looks like this has happened when changing the source of gnupg to gnupg2 with 2.2.4-1ubuntu1.
The old source svn://anonscm.debian.org/pkg-gnupg/gnupg/trunk/ contains the Package as important. The new source https://anonscm.debian.org/git/pkg-gnupg/gnupg2.git contains the Package as optional. gnupg2 was present before, but the did not build a gnupg-Package.
