Hello!
After doing this:
" There is a work-around for the above:
- Download this tar file from my dropbox: http://db.tt/zSChAgJA

In terminal as root:

- cp -R /path/to/downloaded/tar /bin/

- chmod 775 /bin/tar

Now just repeat your packaging and you are done"

Now I have this problem (again):
Can't install. Damaged Installation Package
