To apply a patch in Drupal 8, you will need to follow these steps:

1. Download the patch file and save it to your computer.
2. Navigate to the root directory of your Drupal installation on your local machine using a command line interface such as Terminal on macOS or Linux, or Git Bash on Windows.
3. Run the following command to apply the patch:

1

patch -p1 < /path/to/patch/file.patch

Replace "/path/to/patch/file.patch" with the actual path to the patch file on your local machine.

1. If the patch was applied successfully, you will see a message indicating that the patch was applied. If there were any conflicts or errors, you will see a message indicating that the patch failed to apply.
2. If the patch failed to apply, you may need to resolve any conflicts manually by editing the affected files. Once you have resolved any conflicts, you can try applying the patch again.
3. After applying the patch, you may need to clear the cache in Drupal to ensure that the changes take effect. To do this, go to "Configuration" > "Performance" and click the "Clear all caches" button.
4. It is a good idea to test your site after applying a patch to ensure that everything is working as expected.

To apply a patch in Drupal 8, follow these steps:

1. Obtain the patch file: Sometimes patches are available directly in the issue queue of the Drupal project you are working on. If not, you may need to create a patch file using Git or download it from a reliable source.
2. Place the patch file in the root of your Drupal 8 installation.
3. Open the command line interface (CLI) or terminal and navigate to the Drupal 8 installation directory.
4. Check for any pending updates by running the command: git status (assuming you are using Git for version control).
5. Ensure that you have a clean working directory. If you have any uncommitted changes, either commit or discard them before proceeding. This step is crucial to avoid conflicts.
6. Apply the patch using the following command: git apply -v [patchfilename.patch]. Replace [patchfilename.patch] with the actual name of the patch file you downloaded or created.
7. Once the patch is applied successfully, verify the changes by running git status again. You should see the modified files that were affected by the patch.
8. Commit the changes using git add [filenames] and git commit -m "Patch applied: [description of the change]". Replace [filenames] with the names of the modified files.
9. If necessary, clear the Drupal cache to ensure the changes take effect.

Note: It's important to ensure that the patch you are applying is compatible with the version of Drupal you are using. Additionally, always test the patched functionality thoroughly to ensure it works as intended.
