Drupal 8.x

I'm a total Drupal newb. :D
I have a fresh install of Lightning Drupal 8.8.1

I'm looking through the list of modules, to learn what is installed and what I might want to enable.

I cannot find any info about the module: Simple OAuth Extras
Machine name: simple_oauth_extras

If anyone has a link to the module info page, that would be great.

Is it common to get modules installed by Distirubions that have no info on the Drupal web site?

I have a blog view which I want to override. I am using node twig to do this. But the problem I am facing is the format to be used to get the values. I understand that to get the title or body, we use this - {{ content }} {{ content.body }}. But I want to get the values of the tags in the blog article, authored by, authored on, the image/picture of the author. What is the code to get these values? 

In the view, I have set Format: Unformatted List and Show: Content, Teaser.

Hello,

I have a question. I would appreciate your answer.

How should I provide data to my service correctly? For example in submitForm:

$this->session->set('var1', $name);
$this->session->set('var2', $count);
$form_state->setRedirect('test.task');

Then I have service where I want access the data from session and save in database. Should I read data from session in controller and pass to service by parameter? I guess no but I don't have any other idea. Regards :)

Hello, 

I have my D8 site. I need to apply SSL to the site. 

Step 1: settings.php file, i have this:

//Use HTTPS for Drupal
$_SERVER['HTTPS'] = 'on';
$conf['https'] = TRUE;
$base_url = 'https://www.example.com/';

Step 2: root .htaccess file:

RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Hello,

After numerous more or less flawless updates before (up to 8.7.10) I am trying to update to 8.8.1. I now get this error:

A few days ago, I did a fresh install of Lightning.
I also installed a fresh Drupal 8.8.1, so I could compare.
On my Linux Manjaro desktop using Composer.
I'm a newb re:Drupal, but have been webmastering since '95 using everything from hand written HTML to boxed CMS programs similar to Drupal.

I guess my first question should be, is there a better forum to get help with Lightning?

First problem: I can't install new modules through the web interface:

under admin/reports/updates/install
