Issue migrated manually from dotnet/runtime#33294:

I'm trying to build on a newly-installed Fedora 31 machine. Dependencies have been installed according to the documentation, but I'm getting a timeout when build.sh tries to restore.

(I've temporarily changed some shell scripts in eng/ to execute with bash tracing, plus force msbuild to be called with diag verbosity. Can send the full log.)

It doesn't seem to be a network issue. Accessing that URL from the command line with something like Curl works just fine and returns me the expected JSON data.

This is unrelated to #2199.

master is at 2018c7931.

Also happens in a Ubuntu 19.10 release, with same symptoms: NuGet times out while fetching that JSON, but it's fine if obtained with Curl.

On Ubuntu 18.04 this seems to work just fine. (Might be related to something else, as I've also switched from running things inside VirtualBox to Docker for Mac.)

Hi @lpereira, can you try to clear the http cache by “dotnet nuget locals http-cache --clear” before running restore?
Pls let me know if you still encounter this issue. Thanks!

Triage: Based on the information provided, this issue seems to be particular to the setup. Closing as external.

@ViktorHofer NuGet is not using any special networking logic, so the runtime might be one that can help the customer the most.

[xiangzhai]

dotnet nuget locals http-cache --clear

Doesn't help:

$ .dotnet/dotnet nuget locals http-cache --clear
Clearing NuGet HTTP cache: /home/zhaixiang/.local/share/NuGet/v3-cache
Local resources cleared.

Still repros:

$ ./build.sh -subset clr
