Drupal 8.x

Hi All,

I have am doing a migration from Drupal 7 to Drupal 8.  Its using a MYSQL database (Server version: 8.0.26-0ubuntu0.20.04.2 (Ubuntu)).  With this one particular node when I drush cr and then reload the page I am given the following error:

Notice: unserialize(): Error at offset 0 of 18 bytes in Drupal\Core\Entity\Sql\SqlContentEntityStorage->loadFromDedicatedTables() (line 1288 of core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

I am using drupal 9.2.6

From admin gui I can navigate to admin/content/comment

There I see a list of all published comments.

I want to see the list of unpublished comments. But I do not see any link to such page. (correct me if wrong).

I see in comment.routing.yml there is a route 'comment.admin_approval' and in comment.links.task.yml, there is task with same name with parent comment.admin ... that is /admin/content/comment

However I do not see any link on that page to unapproved comments.

When running the update status module it produces the error "The PHP binary was not found. Scanning is not possible until this is resolved.)

is there a file in the 'update status' structure where this path can be defined?

Following these steps

Manually Updating Drupal 8 Core

I think I was somewhere around version 8.2.x
I followed these steps to manually to update my core.

This is the most tedious method but also the one which is most thorough. The steps involved in this method are as follows:

I'm running Drupal 8 Paragraph distribution. I have created and placed a block and I'm trying to determine the date of first creation. I went to the  custom block library but that is showing an "Updated date". How would I find the date of original creation or placement of the block.

Thanks in advance,

Paul

I have been trying to upgrade from 8.9.18 to 8.9.19 but I keep getting taken to a fresh installation screen. Even after restoring 8.9.18 from the backups, this continues. I'm at a loss to know how to fix this safely. Any help would be greatly appreciated.
