superset upgrade failed from v0.27 to v0.35

Hi :

I upgraded my software according to the manual, from v0.27 to v0.35. After upgrading, I found that the Sources was not available, but the Security and manage were OK. The error message as follows:

@jsynl What database are you using? Superset will use SQLite as the database by default. If there is no special config, it will be saved in

~ / .superset / superset.db

If you need to reinstall and there is no important data, you can try removing superset.db
