If I try to upgrade to a new version of Genesis I got the python error global name 'shell' is not defined.
See the stack trace for more details.

This was reported and solved for 0.6.1 in #469 -- if you are updating to 0.6.1 you must follow the instructions here as workaround: https://bbs.arkos.io/t/genesis-0-6-1-released/1294/2

Thanks!
