That archive is in GNU tar format, which historically differs from ustar format. If you wish to create archives in ustar format use the -H (--format) command line option: tar -Hustar -cf archive.tar ... For a description of the -H option, refer to https://www.gnu.org/software/tar/manual/html_node/Option-Summary.html#IDX81 For a discussion of archive formats supported by tar, please see https://www.gnu.org/software/tar/manual/html_node/Formats.html Regards, Sergey
