After following the instructions at this tutorial https://www.digitalocean.com/community/tutorials/how-to-install-neo4j-on-an-ubuntu-vps , attempting to start neo4j results in the exception
Store and its lock file has been locked by another process: /var/lib/neo4j/data/databases/store_lock
I tried install neo4j 3.5 and 4.0 on ubuntu 18 as well as ubuntu 20 and get the same issues each time; installing on a local ubuntu VM seems to work fine. (more details at the neo4j community: https://community.neo4j.com/t/neo4j-on-ubuntu-vps/20396/3)
Are there any droplet settings that need to be configured?
