The installation stopped, just like in your case. Once I pressed enter it resumed. This has always solved it for me and thus I never gave it much thought.
I think it happened during the install of polymake, but might have been normaliz (or pynormaliz) as well. Not sure but I have encountered it a few times already. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
