Drupal 8.x

Hi. I just installed my first site using drupal following the instruction and using the command "composer create-project Vardot/varbase-project:^8.8.3 mis --no-dev --no-interaction" on a Ubuntu 18.04 system. Installation went well but I get this error in the Reports section.

The site's configuration does not match the associated schema.

Hello,

I'm the https://www.drupal.org/project/hubspot_integration maintainer, I changed my git password but i can not push anything to git anymore with this new password. I uploaded the SSH keys too but no more access 

Could you have a look on my connection issue ? 

Thanks for your help

When this user enters her name and password, this comes back:

The name shxxxx105 is reserved, and cannot be used.

How do I fix this. Hew account is fine and active. Drupal 8.8.3

I've upgraded 2 sites now and I'm getting the same errors on both sites.

Notice: Undefined index: status in _update_requirement_check() (line 117 of /web/core/modules/update/update.install)

Hello, I'm looking for a solution for updating images with a timestamp (image_20200310161333881_TIMING.jpg) pulled from the server.

DESCRIPTION:
I have build a website on Drupal 8.8.1 with a live camera that takes a photo every hour and uploads it via FTP on the server that Drupal is hosted. I created a module that gets the latest image and shows it on a page mydomain.com/webcam. (not very familiar with php)
The code I used to do that is the following:

<?php

namespace Drupal\media_cam_stream\Controller;

roadmap for 2fa basic modules migration to drupal 8 requested.
