Landscape 19.10 - 计算机软件包错误

我已经安装了景观（本地）使用 quickstart 在新的 Ubuntu 1804LTS 安装上安装 19.10https://docs.ubuntu.com/landscape/en/landscape-in​​stall-quickstart。

我已经成功注册了 Ubuntu 1804 LTS 客户端，但是在尝试查看软件包时 https://landscapeurl/account/standalone/computer/3/packages 我在应用服务器日志中收到以下错误

我可以查看已注册客户端的所有其他属性，即硬件、进程等，没有任何错误。

有人能提供进一步的帮助吗？我将不胜感激。

发现问题了；因为我们有公司代理服务器，“no_proxy”环境变量缺少 localhost。我认为 PYCurl 在后台用于查询在 localhost 上监听的包搜索服务；看起来它使用了 http_proxy、https_proxy 和 no_proxy 环境变量。

导航至 lo 接口时使用 tcpdump https://landscapeurl/account/standalone/computer/3/packages。在该跟踪中发现请求我们公司代理服务器的名称解析的数据包。

更新了 /etc/vironment 中的 no_proxy 环境变量，服务器重新启动，现在它可以正常工作
