sqlite3.OperationalError: database is locked

Good afternoon,

I was running the superset normally until yesterday, but now it is giving a database locked error "sqlite3.OperationalError: database is locked", I tried to follow the steps of this question but I could not resolve " how-do-i-unlock-a-sqlite-database ", can you help me?

Thank you

There are many ways of trying to fix the issue on that page. Have you got other processes that are running with the database open? Have you opened the database using the sqlite client to try to close the pending transaction?
