ln: failed to create symbolic link 'protoc': File exists

Error: "failed to create symbolic link 'protoc': File exists"

This error occurs when you try to create a symbolic link called 'protoc', but a file with the same name already exists in the destination directory. To resolve this issue, you can either delete the existing file or choose a different name for the symbolic link.

Please note that without additional context or information about the specific command or scenario in which this error occurred, it is difficult to provide a more specific solution. If you can provide more details, I would be happy to assist you further.
