在转向基于 Debian 的发行版后，我注意到一件非常奇怪的事情。
root@Am-I-Helpful:~# uname -a
Linux Am-I-Helpful 4.3.0-kali1-amd64 #1 SMP Debian 4.3.3-5kali4
(2016-01-13) x86_64 GNU/Linux
的输出apt-get update && apt-get dist-upgrade是：
root@Am-I-Helpful:~# apt-get update && apt-get dist-upgrade

令人惊讶的是：
它说

在另一端，在下一行还指出

这些是要求删除的相同软件包列表！我不明白它是如何出现的。
我的内容/etc/apt/sources.list是：
# deb cdrom:[Debian GNU/Linux 2016.1 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20160120-18:14]/ kali-rolling contrib main non-free
#deb cdrom:[Debian GNU/Linux 2016.1 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20160120-18:14]/ kali-rolling contrib main non-free
#deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main
#deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main
deb http://http.kali.org/kali sana main non-free contrib
deb http://security.kali.org/kali-security/ sana/updates main contrib non-free
deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main
有人可以澄清一下这里发生了什么吗？如何解决这个扑朔迷离的案件？
答案1
没有任何歧义。
Apt 警告您可以删除这些软件包如果你想。如果您使用apt autoremove，它们将被删除。
另一方面，除非您不删除它们，否则它们会定期更新。
