NuGet logs for debugging

I have noticed that sometimes if some references are manually deleted (instead of unsinstalling via the package manager) you see a "Some NuGet packages are missing from this solution. Click to restore" message. And then sometimes when you click on Restore it fails to restore these missing packages. Sadly, all it tells the user is "An error occurred while trying to restore packages. Please try again." And no matter how many times you retry the packages aren't restore.

It would be really helpful to understand what's happening under the hood. So I wonder, where does NuGet log error messages? Or if there is a way to switch to debug logging?

if you run Visual Studio from the command line, for example:

devenv.exe /log "c:\log.xml"

then NuGet will log the error into the specified file.

I downloaded the following copy of NuGet Gallery: fa9319f48d

When I run the restore functionality the following error are logged in the visual studio log file.

Error #1:
