SSL issues after running nuget locals --clear

[livarcocc]

From @aeos on September 21, 2018 16:52

Steps to reproduce

We have a mono project which consists of multiple projects structured like so:
/root
/root/nuget_packages
/root/ProjectA/ProjectA.csproj
/root/ProjectB/ProjectB.csproj
/root/ProjectC/ProjectC.csproj

we build each project, pack them and push them to the /root/nuget_packages folder so that they can depend on each other. Any change we make in a dependency requires a new build/pack/push however we don't update the version number in the csproj because we are doing local development. If another project pulls a dependency, nuget cache sees the same version number and returns the cached package. To avoid this, we first run dotnet nuget locals all --clear. Then when we restore it gets the updated package. This might be a bad practice, there may be a better way.

However, this has worked fine up until we moved to 2.0.

Expected behavior

Prior to dotnet 2.0 this worked without problems

Actual behavior

After updating to 2.0 we receive a stream of errors and a long delay before the restore completes. The errors look like this:

Retrying 'FindPackagesByIdAsync' for source 'https://api.nuget.org/v3-flatcontainer/microsoft.extensions.configuration.azurekeyvault/index.json'. The SSL connection could not be established, see inner exception. Authentication failed because the remote party has closed the transport stream. Retrying 'FindPackagesByIdAsync' for source 'https://api.nuget.org/v3-flatcontainer/microsoft.extensions.configuration.environmentvariables/index.json'. The SSL connection could not be established, see inner exception. Authentication failed because the remote party has closed the transport stream. Retrying 'FindPackagesByIdAsync' for source 'https://api.nuget.org/v3-flatcontainer/microsoft.extensions.configuration.keyperfile/index.json'. The SSL connection could not be established, see inner exception.

Moved to NuGet for initial investigation.

Looks like ASP.NET Core's build hit this as well 2 days ago:

Tracking on nugetgallery repo

[karelz]

@aeos how often does it happen for you?
You mention you upgraded to 2.0. Can you please double check you running truly on 2.0 and NOT on 2.1?
I would not expect the problem to happen on 2.0.

[rrelyea]

@aeos has full version in his first message. 2.1.302 is the SDK being used. His post lists all the runtimes and sdks installed.

[karelz]

@rrelyea how does it answer which .NET Core was used with the nuget client? Why does it comment on "migrating to 2.0" then?

[rrelyea]

I think that:
"NET Core SDK (reflecting any global.json):
Version: 2.1.302"

means that the user ran dotnet restore with 2.1.302 ---
no idea about the moving to 2.0 comment.

[aeos]

Sorry for that typo. You are correct. Moving to 2.1

[aeos]

Here is how I reproduce the issue.

using this simple csproj:

  
    netcoreapp2.1
    Proj.Authority
    1.0.0
    
  
  
    
  

first run dotnet nuget locals all --clear then run dotnet restore
I confirmed with 2 other coworkers that they experience the same thing. One of our coworkers is not seeing the issue.

[karelz]

How often does it happen? Is it 100% repro?
Do you have a repro you can share with us to try it locally?
cc @wfurt

[aeos]

It happens 100% for me and one other. It does not happen to a third. If I use a different package reference there is no errors. I use that csproj file with nothing else to replicate it however xml doesn't appear to work in comments.

[karelz]

If it is 100%, then it is likely something slightly different than the intermittent thing we're chasing down.
You can create your own repo and put the project there, or you can post here step by step instructions how to create such project. You can also post xml via code block: https://help.github.com/articles/creating-and-highlighting-code-blocks/ (the language name is "xml" :)).

[wfurt]

note that the behavior may also depend on your network e.g. do you use proxy, uplink speed and behavior, firewall setting etc. If you have 100% repro @aeos , could you provide packet capture?
(dns, http, https) That should be pretty small for your simple project.

Also note that 2.1.403 is out. Include 2.1.5 runtime had some HTTP fixes regarding proxy and authentication.

[dtivel]

I believe #7314 fixes this.
