我尝试使用https://docs.konghq.com/install/ubuntu/上提供的说明进行安装，还使用了快照存储，但是出现相同的错误。我不知道它是否相关，但是我正在使用预装Ubuntu-20.04的postgres-12.2。 postgres-12.2中的目录结构与以前的目录结构不同。

最后，它是在经过大量研究和无休止尝试之后才完成的。如果您遇到相同的问题，请遵循以下顺序（仅适用于Ubuntu 20.04）：
最好不要使用apt-get或snap安装（至少要等到适用于Ubuntu 20.04的snap才可用）。使用https://docs.konghq.com/install/ubuntu/#packages上的.deb软件包进行安装。下载软件包后，导航至终端中的Downloads文件夹，然后运行以下命令进行安装：
sudo apt-get install openssl libpcre3 procps perl sudo dpkg -i kong-2.0.4。*。deb
不知道第一个命令要安装什么，但根据KONG的官方文档，建议这样做。] >>
在另一个终端中，在postgres中创建一个新用户和数据库以实现KONG连接。
sudo -i -u postgres psql 创建用户kong; 创建数据库kong OWNER kong;
返回到您要安装KONG的终端。尝试运行命令：
sudo kong迁移启动程序
如果一切顺利，请认为自己很幸运，然后转到步骤5。
如果在步骤3发生错误，则为：Error: missing password, required for connect，还有更多工作要做。
kong check[error] no file at: /etc/kong/kong.conf。在目录kong.conf中创建一个名为/etc/kong的文件，然后将https://github.com/Kong/kong/blob/master/kong.conf.default中可用的内容粘贴。kong.conf中的凭据。[在此步骤上创建文件并进行编辑可能会遇到麻烦。]
运行命令
sudo kong start
验证正确的配置。打开浏览器并导航至http://localhost:8001。如果打开某些页面，则表明您的设备上已正确配置KONG。返回终端，然后使用命令停止KONG
sudo kong stop
