I cannot run suu (Linux): with

./suu -u

It errors out with "Unexpected end of file"

With 

./suu -g

the GUI appears, comparison succeeds, but fails to complete any update with "Unexpected end of file"

I am mounting the DVD ISO image.

The DVD checksum is correct.

Merely doing the comparison with ./suu -c works. 

I can run each applicable DUP individually and they succeed.

(All this running on CentOS 6.4 x86_64)
