  • Committer: Teddy Hogeborn
  • Date: 2010-01-01 15:17:12 UTC
  • Revision ID: teddy@fukt.bsnet.se-20100101151712-x20p42nhuvf9lxol
Bug fix: mandos-client needs GnuPG but lacked a dependency on it.  The
Mandos server, on the other hand, did not need GnuPG but declared an
incorrect dependency on it.

* debian/control (Package: mandos/Depends): Removed "gnupg (< 2)".
  (Package: mandos-client/Depends): Added "gnupg (<< 2)".
