Hey! Hello again.. i flash my device again and i did "The Grand DEB Packaging" and again: "tar: unrecognized option '--format=gnu'" .
Then i do what you suggested in that publication:
" - cp -R /path/to/downloaded/tar /bin/

- chmod 775 /bin/tar "
Anew... .deb success ... but Damage Installation Package (any deb).

This time, i did a backup of my "tar" archive and restore it... no solution.

Thanks for all the inconvenience and hope you understand that i'm experiencing, I do not know anything about programming but read. I'm an architect, i hope my intention to create simple packages not be truncated.

Pd. apt-get install gnu-tar -> package not found.
Cheers!
