I just installed Spacemacs on Ubuntu and key SPC it not working. When I press it, Spacemacs shows the message
Buffer is read-only: #<buffer *spacemacs*>
I'm running Ubuntu 16.04 and and Emacs 24.
Should i configure anything else? I'm have been following this link https://gist.github.com/shaybix/4dd95830909daa59207635951a533127
