我正在使用 debsecan 在我的 Debian jessie 盒子中安装安全更新。我认为安装所有报告的软件包后，我不应该有任何来自 Debian-Security 存储库的待更新更新，但事实并非如此：
#: debsecan --suite jessie --format packages --only-fixed
#:
#: apt-get --simulate upgrade | grep "Debian-Security"
Inst libapt-inst1.5 [1.0.9.8.3] (1.0.9.8.4 Debian:8.9/oldstable, Debian-Security:8/oldstable [amd64])
Inst libsoup2.4-1 [2.48.0-1] (2.48.0-1+deb8u1 Debian-Security:8/oldstable [amd64])
Inst libsoup-gnome2.4-1 [2.48.0-1] (2.48.0-1+deb8u1 Debian-Security:8/oldstable [amd64])
Inst libnet-dns-perl [0.81-2] (0.81-2+deb8u1 Debian:8.9/oldstable, Debian-Security:8/oldstable [amd64])
Conf libapt-inst1.5 (1.0.9.8.4 Debian:8.9/oldstable, Debian- Security:8/oldstable [amd64])
Conf libsoup2.4-1 (2.48.0-1+deb8u1 Debian-Security:8/oldstable [amd64])
Conf libsoup-gnome2.4-1 (2.48.0-1+deb8u1 Debian-Security:8/oldstable [amd64])
Conf libnet-dns-perl (0.81-2+deb8u1 Debian:8.9/oldstable, Debian-Security:8/oldstable [amd64])

我不明白为什么 debsecan 不报告这些包：
#: debsecan --suite jessie --format packages | grep "libapt\|libsoup\|libnet-dns"

有什么提示吗？谢谢。
