The error message you're encountering indicates that the system is trying to change directory to ../../drivers/kernelsu but cannot find the specified directory. This suggests that either the directory does not exist, or the path is incorrect. The script is part of the KernelSU installation process, which seems to be a custom kernel patching solution that modifies the kernel to allow additional features or optimizations. KernelSU is often used in conjunction with custom ROMs and requires a specific setup to function correctly. Here are some steps to troubleshoot the issue:

  1. Verify the Directory Path: Ensure that the directory ../../drivers/kernelsu exists in your file system. If it does not, you may need to recreate it or adjust the path in your script to point to the correct location.
  2. Check Permissions: Sometimes, the script may not have the necessary permissions to access or modify certain directories. Verify that the user running the script has the appropriate permissions.
  3. Consult Documentation: Review the KernelSU documentation for any specific instructions related to your kernel version and device model. There may be additional setup steps or dependencies that need to be met.
  4. Update KernelSU: Ensure that you are using the latest version of KernelSU that is compatible with your kernel version. Older versions may have compatibility issues with newer kernels.
  5. Seek Community Help: If you are still facing issues, consider reaching out to the KernelSU community or forums. Other users may have encountered and resolved similar issues, and their insights could be valuable.

By following these steps, you should be able to identify and resolve the issue preventing KernelSU from installing correctly.
