Então, tudo estava bem, até que eu atualizei para o Ubuntu 17.10. Esta é a saída ao tentar iniciar o ipython (aquele baseado no python 2.7) Eu tentei reinstalar o ipython e não vai funcionar. Tho, ipython3 parece estar funcionando bem.

Por favor, eu já tentei limpar e reinstalar TUDO. Mesmo python2.7.
