Updating

It's assumed that Bookstack was installed by the Ubuntu script.

1. Very important, as always backup your Bookstack instance
2. by default Bookstack is installed under /var/www/bookstack, if that wasn't changed, then go there
3. try to pull the latest changes: git pull origin release
4. if that fails because there are updated files in the directory, run: git config core.fileMode false
5. then: composer install --no-dev
6. last one: php artisan migrate

Also don't forget to clear cache:

php artisan cache:clear
php artisan config:clear
php artisan view:clear
