The configuration cannot be imported because it failed validation for the following reasons

You need to ensue that swiftmailer and mailsystem modules are installed in your config export - take a look at core.extension.yml

@Mohan6695 this is the problem with your config export. You either need to delete mailsystem.settings.yml, swiftmailer.message.yml and swiftmailer.transport.yml or enable those two modules - but you can't sync config for modules that aren't installed on your system.

You just need to delete these configurations.
drush config-delete mailsystem.settings
drush config-delete swiftmailer.message
drush config-delete swiftmailer.transport

OK

It works for me in other similar situations。

Best wishes!

@Mohan6695, Is this still a problem? If you have resolved this what did you do?

I get these errors in d9.2

drush cdel CONFIGURATION_NAME

Example: drush cdel mailsystem.settings

Be sure the theme or module is outdated before you run these commands! I was able to remove all of my errors by removing these old dependencies.

#6 worked for me. Thnaks

I got similar issues when to import config:

- Error about three blocks depends on 2 custom modules
- Three custom blocks are:
-- 'block.block.solosegmentsearchblock',
-- 'block.block.header_search_block',
-- 'block.block.ul_com_theme_header_search_block'

My solution is run the drush command:

drush sql:query  "DELETE FROM config WHERE name IN ('block.block.solosegmentsearchblock', 'block.block.header_search_block', 'block.block.ul_com_theme_header_search_block')"

My platform: Drupal 9 and Drush 10

Just a note after a recent bad experience. Bad, bad, bad idea to run something like drush sql:query "DELETE FROM config WHERE name IN ('core.entity_view_display.paragraph.nested.default')" on anything unless you are absolutely sure, sure, sure you don't need the config.

I just did this in order to get a view imported, and ended up removing the configuration that opens my accordion paragraphs. Had to restore backup to get it back.

Which leads me to the next question: Is there another general workaround for this problem other than deleting configurations?:

Configuration mailsystem.settings depends on the mailsystem extension that will not be installed after import.

#6 works for me as well!

#6 works for me as well!

#6 worked for me as well. The problem is that it created an entirely new problem by deleting the configuration. Fortunately I was able to copy the configuration from a duplicate site. But, we really need another solution to this problem.

I have the same problem, where I need to delete configuration from my three custom modules like

Configuration admin_quotation_settings.settings depends on the admin_quotation_settings extension that will not be installed after import

I would like to know avoid this situation in future. Why does it happen, how to remove the dependency?

What is the reason for this error?

This is how I resolved my issue: https://www.drupal.org/project/drupal/issues/3335049#comment-14881197

Essentially, a configuration exists in the source site that does not exist in the destination site(s). So, the strategy, other than deleting the configurations in the destination site config table, is to make sure the configuration in question is duplicated in the source site.

I do not know what the issue is with "admin_quotation_settings", but if it's in a module that's enabled in the source but not the destination, you can easily fix the problem by enabling that module in the destination.

If, as in my case, the configurations on both the source and destination sites are exactly the same, then you can try what I did: Go to the settings page for that configuration on the destination site, and simply re-save it. I know, simple. But it worked for me.

Deleting those configs works

Have Same issue

Having same issue in 9.5. Modules don't list these dependencies and are in the extensions.yml. Could this be a config split issue?

I exported a view as a single item, and after deleting and re-creating a field that is included in the view (same machine name) I try to run the import, all on the same site. Validation fails and it won't let me import, stating: "Configuration update.settings depends on the Update Manager module that will not be installed after import."

I don't understand how Update Manager is a dependency of a view, and there is no reference to it in the view export code either. It wasn't installed when I exported and isn't installed when I attempt to import either. Very strange behavior, I don't have config split installed. Drupal 10.2.3.

See also the How to fix "The following module is missing from the file system..." warning messages documentation page for this problem.

For a personal D10 site, I created a new view in my local version that I tried to import into the live site. I got this message: "Configuration block.block.workflowtransitionform depends on the theme that will not be installed after import."

I exported that config and it had this:

...
dependencies:
  module:
    - workflow
  theme:
    - null
id: workflowtransitionform
theme: null
...

I replaced both instances of "null" with "claro", imported that config on admin/config/development/configuration/single/import, and then I was able to import the view.

I have no idea where "null" came from, but if this is a common problem for a lot of people it might be easiest to create a "config repair" contrib module that would look for and fix such things.
