I have a test tar file named f.tar.gz.

>>> import tarfile
>>> tarfile.open('f.tar.gz')
<tarfile.TarFile object at 0x7f8a652fdad0>
>>> tarfile.is_tarfile('f.tar.gz')
True

and for you,

>>>tar = /root/testtar.tar.gz
>>> import tarfile
>>> tarfile.is_tarfile(tar)
False

So your "tar file" is not a real tar file. No wonder it is failing
to open. Does it take rocket science to figure this out ?
