Drupal 8.x

Attempting to upgrade from from D7 to D8 or D9.

Good morning,

One of my Drupal 8 websites was behaving properly until I started updating long-awaited modules. Once I tried to update a module it gave me an error message like the following. May I know how to handle this type of issue? Are there any standard processes to handle these types of errors?

In my Bartik theme, there is a pencil icon, which leads to the contextual edit menu ("Configure block" / "Remove block" / "Edit menu" / ...). There are, however, a couple of problems with this icon. First, but let's skip this one, it's very ugly.
