Error after upgrading to latest Traccar server ... traccar-linux-arm-6.14.2.zip
Your Traccar service is stuck during startup because Liquibase (the database migration tool used by Traccar) has detected a stale lock in your database. This usually occurs if the Traccar service was forced to stop, killed, or crashed while it was performing a database schema update.
