理解在哪里引用包名？

Question

我正在尝试理解Unable to locate package错误。

在我的例子中，我正在尝试安装zcash。在安装依赖项并在初始安装之后，我更新了我的sources.list文件：

echo "deb [arch=amd64] https://apt.z.cash/ jessie main" | sudo tee /etc/apt/sources.list.d/zcash.list

然后我运行了sudo apt-get update

查看/var/lib/apt/lists，我可以看到已安装的包(在本例中，是从zcash)：

/var/lib/apt/lists$ ls
apt.z.cash_dists_jessie_main_binary-amd64_Packages
apt.z.cash_dists_jessie_Release
apt.z.cash_dists_jessie_Release.gpg

然而，当我运行sudo apt-get install zcash时，它似乎认不出zcash这个名字：

Reading package lists... Done Building dependency tree        
Reading state information... Done 
E: Unable to locate package zcash

我想应该有一个名称转换文件(例如，zcash到/var/lib/apt/lists中引用的文件)--我是正确的吗？

应该将apt包的名称引用存储在哪个文件/目录中？我将如何检查和调试这个？

Answer 1

我刚看到这个所以我测试了..。

在VirtualBox (amd64 netinstall，只有“标准系统实用程序”和"ssh服务器“)的基本安装上，我在安装zcash时没有问题.不过，我猜你没有给回购加钥匙.

编辑了/etc/apt/sources.list并添加了行

deb https://apt.z.cash/ jessie main

添加apt-transport-https

apt-get install apt-transport-https

做一个apt-get update。啊..。恢复gpg键错误。导入/添加存储库的密钥-

wget -qO - https://apt.z.cash/zcash.asc | sudo apt-key add -

然后是apt-get update然后是apt-get install zcash
