package samba (not installed) failed to install/upgrade: il sottoprocesso vecchio script di post-installation ha restituito lo stato di errore 1

[Fendervr]

I was opening a pdf file saved in a windows partition (FAT32) to send the information requested by Ursula Junque" <email address hidden> related to Bug 820023. Selecting text on the file I obtained this error.
I think that the two bug is linked. Many thanks
