每当我尝试运行安装包选项时，我会收到一条错误消息“没有可用的安装包”

控制台显示以下跟踪：

Package Control: Error downloading channel. b'curl: (77) error setting certificate verify locations:\n  CAfile: /usr/lib/ssl/certs/ca-certificates.crt\n  CApath: /etc/ssl/certs' downloading https://sublime.wbond.net/channel.json.
error: Package Control
There are no packages available for installation

如果我添加http://sublime.wbond.net/repositories.json作为通道，安装软件包开始显示软件包列表。但是，当我尝试安装一个软件包(例如Pretty JSON)时，我再次收到与安全证书相关的错误，并带有以下控制台跟踪：

reloading Packages/User/Preferences.sublime-settings

欢迎任何建议使软件包控制与安全渠道一起工作。

用于包装控制的附加调试跟踪：

启用对软件包控制的调试我得到以下跟踪：
