Cannot complete dotnet restore because some requests timed out after 100000ms #2945

Closed Konard closed 6 years ago

Konard commented 8 years ago

Trying to make a simple hello world application using instructions from https://www.microsoft.com/net/core#windows

We tried dotnet restore, but it is timeouts too much.

When we tried dotnet restore --disable-parallel it became better, but still it is not possible to download all packages.

The main problem we suspect is a slow and unstable internet connection (4G). Is it possible to increase a 100000ms timeout limit?

There is currently not an option to increase the timeout duration. Could you provide a log file for both dotnet restore and for dotnet restore --disable-parallel?

Have you tried a different version of Windows or a the same steps on a different network?

Also, this issue reminds me of https://github.com/dotnet/cli/issues/1732. There are a couple suggestions for different scenarios and network configurations.

.NET Core was installed using https://go.microsoft.com/fwlink/?LinkID=798398 (https://download.microsoft.com/download/4/6/1/46116DFF-29F9-4FF8-94BF-F9BE05BE263B/packages/DotNetCore.1.0.0.RC2-SDK.Preview1-x64.exe)

And this is a real machine, not a virtual machine. So there is no possibility to just install other version of Windows, and this is the only network available.

... and this working ok.

joelverhagen commented 8 years ago

Is this a full log? Are all of the requests failing like this? Or do requests at the beginning of execution work just fine and, only after a while, do requests start timing out? One issue is it seems that the --disable-parallel switch still allows multiple concurrent HTTP requests. I will investigate whether this is intended.

Some files was downloaded ok. This was a part of log of last rerun of restore (so it contains only those files that was non downloaded ok). We will try to run restore again. And I`ll provide a full log in txt file.

Konard commented 8 years ago

The log is truncated by cmd, so only the end of log is available: dotnet restore log.txt

There are videos of the process: https://www.youtube.com/watch?v=y64jBe8ecMU https://www.youtube.com/watch?v=XZlrqeAQ5sg https://www.youtube.com/watch?v=v4nOgwQdegQ

Does executing nuget.exe restore project.json also hang? Try using this version of NuGet.exe: https://dist.nuget.org/win-x86-commandline/v3.5.0-beta/NuGet.exe

I'm on an odd/crappy Internet connection which for some reason reacts badly to many concurrent connections. --disable-parallel doesn't seem to actually disable parallel HTTP connections, unfortunately.

Trying the v3.5.0-beta doesn't seem to change anything for me.

It's also unfortunate that the timeout value itself can't be adjusted.

I've improved -DisableParallel on NuGet.exe and checked the change into our dev branch. The -DisableParallel (and --disable-parallel on dotnet restore) switch only impacts specific parts of the restore process. I have extended this to include HTTP concurrency during restore.

Could you give this prerelease build a try and see if it solves your problem? NuGet-dev-1506.zip

You can use nuget.exe restore instead of dotnet restore to try out this prerelease build.

Hey @Konard, have you had a chance to try this newer nuget.exe that supports disabling parallel HTTP? If this resolves the problem, I would still like to keep this issue open to track potential improvements in these two areas:

  1. Configuring HTTP timeout value
  2. Setting arbitrary levels of HTTP parallelism (maybe 1 is too slow, 16 is too much for your connection, but 4 is the "sweet spot").

Yes, the nuget.exe restore -DisableParallel successfully downloaded all packages.

I had same issue and here is my solution:

  1. Disable all other network interfaces.
  2. Open %TEMP%\NugetScratch and delete all files.
  3. Delete project.lock.json (if exists) from your repository folder.
  4. Run dotnet restore and it should restore them successfully.

Here is my dotnet info:

Some problem with VirtualBox Host-Only Network, Disabling the VirtualBox Adapter fixed it for me.

Thanks for reporting this issue. We have not been able to reproduce this issue. If you are still able to reproduce this with the latest NuGet version, please provide additional steps.
