Please try to use the --no-preserve=true flag with kubectl cp command. It will pass --no-same-owner and --no-same-permissions flags to the tar utility while extracting the copied file in the container.

GNU tar manual suggests to use --skip-old-files or --overwrite flag to tar --extract command, to avoid error message you encountered, but to my knowledge, there is no way to add this optional argument to kubectl cp.
