When updating, the "Global settings" step could fail with an error like:

TypeError: Dictionary.transform_value() got a non-dict: [..]

Werk #19411 changed the format of the global setting "Use new service names" (use_new_descriptions_for) from a list of plugins to a per-plugin mapping. The update converted this setting installation-wide, but not the site-specific copies of it, such as the per-site settings of a remote site. A site-specific setting left in the old format then caused the error above. The update now converts the site-specific settings as well.
