Laravel 5.8 installation issue on Ubuntu 18.04 ("DB name seems incorrect")

Hello,

I followed all the steps outlined in the following two links:

internet link #1 : “Setting Up A Laravel Local Dev Environment On Ubuntu” (by Andrew Brooks)

internet link #2: Install Laravel PHP Framework on Ubuntu 16.04 | 17.10 | 18.04 with Apache2 and PHP 7.2 Support (Website for students dot com)

The database laravel was created and my .env file is identical to the tutorial.

My browser displays the following error : https://ibb.co/KVRyp8k

I constantly get the following error in the terminal: https://ibb.co/kMZ0Hhd

Any help is greatly appreciated.

Thank you for your time.

K.
