运行后如何知道及其字段对应的是apt-cache show <package>哪个存储库？sources.list<package>Filename:
在这种情况下， 中的存储库很少，因此我可以在所有存储库前面sources.list添加路径，并检查它是否有效。pool/main/c/cntlm/cntlm_0.92.3-1+b1_amd64.deb
但是，如果我有很多存储库sources.list，我将如何查看该包位于哪个存储库中？

您无法直接从 的输出确定这一点apt-cache show。还有另一个apt-cache命令可以告诉您各个存储库中可用的版本，policy；那些带有候选版本的都是 所示的包的潜在来源show。
apt-cache policy cntlm
将提供您想要的信息。
