teamcity - Team City Build step fail with "Could not find file 'C:\Users\tfsbuild\.nuget\packages\system.xml.xmldocument\4.3.0\system.xml.xmldocument.nuspec'" -

trying "restore" .net core 2 project in team city ,

could not find file 'c:\users\tfsbuild.nuget\packages\system.xml.xmldocument\4.3.0\system.xml.xmldocument.nuspec'.

in build log. know might bit try building team city thinking migh have figured out? since both nuget installer step , dotnet core restore give same error maybe i've overlooked?

it seems related user permissions. changing build agent custom domain user system solved problem.
