Sorry about the rough start. Guix-land is a real adventure sometimes!

Thanks for specifying the command and config.scm.
Did you follow the manual? (e.g. authorize the keys for both servers above?)

I suspect you did not as guix was trying to build stuff (normally we 
have substitutes for almost everything if you either run init without 
pulling first (=guix 0.15) or pull to a commit a week ago or so.

Getting substitutes to work is crucial if you are not very patient. The 
hash mismatches are a plague brought by changes upstream which are NOT 
retroactively fixed.

You can check the availability of substitutes with "guix weather".

With substitutes working and available init should not take more that 10 
min on a recent machine. It would probably be a good idea to state this 
in the manual.

If you want to hack on guix you will have to update guix above 0.15.
