我想安装开发版本按照以下说明 https://www.torproject.org/docs/debian.html.en#development在我的 ubuntu 14.04 上，但每当我运行命令
sudo apt-get update
发生一些错误：

E: Some index files failed to download. They have been ignored, or old ones used instead.
之后我运行这个命令
sudo apt-get install tor deb.torproject.org-keyring
发生错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package deb.torproject.org-keyring
E: Couldn't find any package by regex 'deb.torproject.org-keyring'
我该如何修复它？

发生这种情况是因为您遵循了 Debian Jessie 说明。您需要将说明上方的下拉菜单更改为 Ubuntu Trusty Tahr。:)
首先，您需要从存储库中删除 Jessie 条目。为此，请在终端中输入以下命令：
sudo rm /etc/apt/sources.list.d/jessie-main.list
接下来需要更新 apt：
sudo apt-get update
完成此操作后，您将需要继续执行 Ubuntu Trusty Tahir 说明。
删除软件源的另一种方法是使用下面的图标打开“软件中心”。
在软件中心内，单击“Ubuntu 软件菜单”中的“软件和更新”链接，如下图所示。
在“软件和更新”中，单击“其他软件”选项卡，并确保我在下面更新中勾选的 2 个选项已从您的源中删除。如果没有，请将其删除。
完成后，关闭该窗口，它将更新存储库。
