Email Inbox Module Not found error on fresh install to ERPNext 8.0

I’ve got this message after doing a fresh install of ERPNext 8.0 on a fresh install of ubuntu server 16.10. When I click on the Email Inbox under tools I get Module Not Found. This occurs also when I click on explore.

Is there I fix I should know about as a search of discuss.erpnext doesn’t return anything valid.
