从ISO文件安装Kali Linux后，我们可能需要手动更新APT源。
使用官方的存储库列表。
本教程将向我们展示如何将Kali Linux APT存储库添加到Sources.List。

APT需要将软件存储库用于下载软件包并将其安装到计算机上。
我在kali linux滚动发布2019.4上这样做。
让我们开始。

$cat /etc/os-release 
PRETTY_NAME="Kali GNU/Linux Rolling"
NAME="Kali GNU/Linux"
ID=kali
VERSION="2019.4"
VERSION_ID="2019.4"
VERSION_CODENAME="kali-rolling"
ID_LIKE=debian
ANSI_COLOR="1;31"
HOME_URL="https://www.kali.org/"
SUPPORT_URL="https://forums.kali.org/"
BUG_REPORT_URL="https://bugs.kali.org/"

将root或者用户身份登录并启动终端。

在终端中，检查系统中存在的APT存储库的当前列表。

$cat /etc/apt/sources.list

如果没有APT存储库，请粘贴下面的代码以添加它们。

sudo tee -a /etc/apt/sources.list<<EOF
deb http://http.kali.org/kali kali-rolling main non-free contrib
deb-src http://http.kali.org/kali kali-rolling main non-free contrib
EOF

上面的命令将在/etc/apt/sources.list中添加标准和源存储库。
确认它们已添加。

$cat /etc/apt/sources.list
# 
# deb cdrom:[Debian GNU/Linux 2019.4 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20191125-10:47]/kali-last-snapshot contrib main non-free
#deb cdrom:[Debian GNU/Linux 2019.4 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20191125-10:47]/kali-last-snapshot contrib main non-free
# This system was installed using small removable media
# (e.g. netinst, live or single CD). The matching "deb cdrom"
# entries were disabled at the end of the installation process.
# For information about how to configure apt package sources,
# see the sources.list(5) manual.
deb http://http.kali.org/kali kali-rolling main non-free contrib
deb-src http://http.kali.org/kali kali-rolling main non-free contrib
