Impossible to update module after upgrade 1.5 -> 1.6

[veptune]

Hello all,

 

After my upgrade from 1.5 to 1.6 all the front office display is messed up.

 

I read that this is because i need to upgrade modules too.

 

And i got this error when i update any module (even official, like cart block or horizontal menu).

 

2 errors

    There was an error while extracting the module (file may be corrupted).
    Module blockcart can't be upgraded:
 

 

Of course, permission on my modules folder are 777

 

Actually, it is the same problem than here :

But there is still no answer on this thread.

 

This is really a big issue, i hope the PS team will hande that
