Cahier Jupyter - OSError [Errno 2] Aucun fichier ou répertoire de ce type

Question

J'ai dû installer Jupyter pour compléter les projets d'Udacity. Après avoir suivi les instructions, et exécuté Jupyter, aucun des cahiers n'ouvrirait. Ceci est la sortie du journal:

[W 06:54:04.215 NotebookApp] The signatures database cannot be opened; maybe it is corrupted or encrypted. You may need to rerun your notebooks to ensure that they are trusted to run Javascript. The old signatures database has been renamed to /home/aulon/.local/share/jupyter/nbsignatures.db.bak and a new one has been created.

Je googlé et trouvé quelques problèmes similaires here, here et here, sans succès.

J'ai installé Anaconda, toujours le même problème.

Toute aide est très appréciée.

Si je ne peux pas résoudre ceci, comment puis-je désinstaller complètement tout ce qui concerne jupyter et anaconda? J'utilise Ubuntu 16.04.

Sinon, y a-t-il un autre moyen d'ouvrir un bloc-notes python sans jupyter? Peut-être Spyder?
