Trying to update:

PM> Get-Package -Updates
No package updates are available from the current package source.

What's broken in my installation?

Update:

I use VS Express 2012 for Web Update 2 and NuGet 2.2.40116.9051
The package updates are not shown in NuGet GUI too.

Solution

It seems to be a bug in NuGet, here is a bug report from somebody else: http://nuget.codeplex.com/workitem/3289

The workaround is simple: updates are working for individual projects, not for the solution.
