Question

只是让您知道我是Linux的新手，现在已经尝试了一段时间，以在Linux Ubuntu 18.04上发布ASP.NET Core网站。

我已经在Visual Studio 2017的ASP.NET Core 2.1中开发了一个测试项目，并且试图将其发布在Ubuntu 18.04上。

我已按照本文所述执行以下步骤：

https://blog.todotnet.com/2017/07/publishing-and-running-your-asp-net-core-project-on-linux/

我不想发布文章中描述的测试网站，而是要发布自己的网站。我正在Visual Studio 2017中发布网站。

将网站发布到Linux上的工作目录后，我具有以下文件：

Docker.DotNet.dll
TestCoreWebsite1.deps.json
TestCoreWebsite1.dll
TestCoreWebsite1.pdb
TestCoreWebsite1.runtimeconfig.json
TestCoreWebsite1.Views.dll
TestCoreWebsite1.Views.pdb
web.config

当我在Linux终端“ journalctl -xe”中键入命令时，出现以下错误：

realpath(): Permission denied
System.UnauthorizedAccessException: Access to the path '/var/www/.dotnet' is denied. ---> System.IO.IOException: Permission denied
--- End of inner exception stack trace ---

at Microsoft.DotNet.Cli.Program.Main(String[] args)
tcore.service: Main process exited, code=exited, status=1/FAILURE
tcore.service: Failed with result 'exit-code'.

它告诉我“ /var/www/.dotnet”被拒绝。实际上，这个路径甚至不存在。

我该怎么做才能解决此问题？

奇怪的是，按照本文的步骤进行操作仍然无效。

是否存在问题，因为我安装了.NET Core运行时的多个版本？

将ASP.NET Core发布到Ubuntu
