Emacs does not run after package updating

Question

What should I do? After just updating packages my Emacs installation does not initialise. I tried the same process in two Macs with the same result. The error message (using --debug-init ) is:

 Debugger entered--Lisp error: (void-variable left)

There is a solution for this in https://github.com/milkypostman/powerline/issues/79 . It seems to be a known bug in powerline.el .
