Anything else relevant?
To use ng update it is possible to update the local pacakge to latest version by increasing it in package.json by hand and do an npm install. Then with the lastest version ng update always works. It is the problem with the mechanism to preinstall the lastes version on ng update command.

I also tried to route the global node_modules to a different folder. That works for all global packages, but not for that command. It will always use the users directory.
