I ran into an odd problem today whereby all of a sudden the
dotnet restore command (also a problem if you call
dotnet pack) failed with the following errors:
C:\Program Files\dotnet\sdk\2.1.300-preview2-008533\NuGet.targets(114,5): error : Unable to get repository signature information for source https://www.myget.org/F/[blahblah]/api/v3/repository-signatures/index.json. [D:\...blah.sln] C:\Program Files\dotnet\sdk\2.1.300-preview2-008533\NuGet.targets(114,5): error : Unable to parse allRepositorySigned information from https://www.myget.org/F/[blahblah]/api/v3/index.json. [D:\...blah.sln]
I tried flushing dns cache, resetting network adapters, clearing
NuGet cache, uninstalling and reinstalling
This is what worked:
I was calling
dotnet pack on the solution file. I ran
dotnet pack on each individual project in the solution from the command line, now it works on the solution file. Go figure.
You probably don’t need to run it on every project, I imagine one will do, but I’m unable to test that as now everything is working. I have confirmed it is working by clearing my
NuGet cache again, cloning a new version of my repository and running
dotnet pack, and the restore runs fine once again.
As an aside, pinging
www.myget.org on the problem machine returns
myget-www-prod-eu-west.cloudapp.net. Not sure if this has anything to do with it (some cross domain restriction, perhaps?). But then again, now pack works and I can see in the logs the restore took place with
