我最近安装了 Debian 11，然后开始乱搞，最后找不到任何带有 的软件包apt。例如，当我运行sudo apt install ifconfig它时，它返回：E: Unable to locate package ifconfig。我已经读了十几页，它可能与我的文件有关sources.list。
我检查了文件，一切似乎都很好。内容sources.list：
deb http://deb.debian.org/debian bullseye main contrib non-free
deb-src http://deb.debian.org/debian bullseye main contrib non-free
deb http://deb.debian.org/debian-security/ bullseye-security main contrib non-f>
deb-src http://deb.debian.org/debian-security/ bullseye-security main contrib n>
deb http://deb.debian.org/debian bullseye-updates main contrib non-free
deb-src http://deb.debian.org/debian bullseye-updates main contrib non-free
#buster-backports
deb http://deb.debian.org/debian buster-backports main contrib non-free
deb http://archive.debian.org/debian stretch main contrib non-free
有人知道如何解决这个问题吗？
的输出LC_ALL=C sudo apt update是：
Hit:1 http://deb.debian.org/debian bullseye InRelease
Hit:2 http://deb.debian.org/debian-security bullseye-security InRelease

你sources.list看上去不错*，apt update工作，apt search工作。
sudo apt install ifconfig返回的原因E: Unable to locate package ifconfig是没有名为 的包ifconfig。
请阅读我如何找出哪个包拥有某个文件？可执行文件名为ifconfig 在名为的包中net-tools.这应该有效并为您提供ifconfig：
sudo apt install net-tools
注意，确实apt search ifconfig在几个其他软件包中找到了此软件包。您声称“找不到任何带有apt”的软件包，这似乎没有道理。
* 除了这些non-f>，n>我假设它们是发布nano sources.list（或其他文本编辑器）截断行时打印的内容的结果，而不是发布实际的满的内容sources.list。
