Initial Update: Saturday, 30 July 2016 02:01 UTC
We are actively investigating issues with Visual Studio Team Services. Some customers may see a build failure with Nuget errors if they have below conditions.
1) If you have at least one VSTS Nuget package source
2) If you have more than one NuGet restore task in the build definition.
The symptom is, the second NuGet restore build task fails.
You will see an error message like below :
Unable to find version ‘1.8.1’ of package ‘Microsoft.Cosmos.Client’.
##[debug]rc:1
##[debug]success:false
##[error]Error: C:BAagentWorkerToolsnuget.exe failed with return code: 1
##[error]Packages failed to install
##[debug]task result: Failed
Work Around:: If you have the above repro then, you go to your agent pool in web UI, right click, and choose “Update All Agents”
Next Update: Before 30 July 2016 06:00 UTC
We are working to resolve this issue and apologize for any inconvenience.
Sincerely,
Bapayya
