Laravel + SQLite = SQLSTATE[HY000]General Error: 8 attempt to write a readonly database

You need to run two commands

First, change ownership of the Laravel directory to web group:

sudo chown -R :www-data /var/www/yourLarvelFolder

Second, give privileges over storage directory so it can be writable:

sudo chmod -R 775 /var/www/yourLarvelFolder/storage
