Unable to deactivate or uninstall theme

Description

You get the following error message during a Shopware update or when deactivating or uninstalling a theme:

Unable to deactivate or uninstall theme "{{ themeName }}". Remove the following assignments between theme and sales channel assignments: {{ assignments }}.

Cause

As the error message says, a theme must no longer be assigned to a sales channel so that it can be deactivated or uninstalled.

Solution

With this message, Shopware asks you to remove the assignment of a theme (see {{ themeName }}) from the sales channel (see {{ assignments }}).

In this case, simply assign the Shopware Standard Theme to the corresponding sales channel.
