Kali rolling based on Kali 2017.3 on a Pi 3 that's been working and stopped after updating today. Tried removing metasploit and reinstalling it, same error:

root@pi2222:/home/support# msfconsole
Could not find rake-12.3.0 in any of the sources
Run `bundle install` to install missing gems.

Is this an arm specific package issue or more general across Kali?
