c# - 在 .net Rider IDE : Failed to download package `x` The HTTP request to GET `x` has timedout after 100000ms 中恢复解决方案的 nuget 包

Question

我有 ArchLinux 发行版，我是第一次在 Linux 上测试 .Net SDK。我安装了 JetBrains Rider IDE 的试用版。我创建了新的 ASP.Net Core 项目，但在构建解决方案或手动恢复解决方案的 Nuget 包时，我在 Event Log 窗口中收到此错误消息:

1:51 PM Can't restore NuGet packages in integrated projects Failed to retrieve information about 'Microsoft.AspNetCore.WebUtilities' from remote source 'https://api.nuget.org/v3-flatcontainer/microsoft.aspnetcore.webutilities/index.json'. Settings Log Packages folder

1:51 PM Restore failed Failed to retrieve information about 'Microsoft.AspNetCore.WebUtilities' from remote source 'https://api.nuget.org/v3-flatcontainer/microsoft.aspnetcore.webutilities/index.json'. Settings Log Packages folder

这是 Log 窗口的内容，因为它的内容非常大，我将其上传到谷歌驱动器:Here

有人遇到过这个问题吗？另外，为什么 rider 试图获取地球上所有的 Nuget 包？我没有对 Microsoft.Win32.Registry 的引用，并且这些错误行之一提示:

COREMINIMAL: Failed to download package 'Microsoft.Win32.Registry.4.4.0'

之后，尝试 dotnet restore 我得到以下输出:

$ dotnet restore

Permission denied to modify the '/opt/dotnet/sdk/NuGetFallbackFolder' folder.

Here are some options to fix this error:
---------------------
1. Re-run this command with elevated access.
2. Disabled the first run experience by setting the environment variable DOTNET_SKIP_FIRST_TIME_EXPERIENCE to true.
3. Copy the .NET Core SDK to a non-protected location and use it from there.

输出太长了，大部分是关于重试下载包。

根据随附的 Rider 和 dotnet 日志，此问题与 Rider IDE 无关。

似乎有一些 dotnet 的初次体验功能需要访问 dotnet/sdk/NuGetFallbackFolder 但未提供，因此您在日志，但这可能不是真正的根本原因。

根据日志消息 The download of 'https://api.nuget.org/v3-flatcontainer/microsoft.win32.registry/4.4. 0/microsoft.win32.registry.4.4.0.nupkg' 超时，因为在 60000 毫秒内没有收到数据。

您可能应该检查您的网络和 dotnet/NuGet 设置。
