Error in running mt_prep_snap in Linux

I did it and i see the same errors, I tried also to work in my extern disk but the same thing.

really I dont’ know where is the fault, I did the change you gave me yesterday but the problem is still remain . yesterday I processed my data in snap one more time i did a new export from snap to stamps but the same problem.
i hope that you can see what i can not see. thank you a lot.
