package cryptsetup 2:1.6.1-1ubuntu7 failed to install/upgrade: η υποδιεργασία installed post-installation script επέστρεψε κατάσταση λάθους 1

[Kostas N. Andreou]

cryptsetup was on upgrade procedure, but there are no crypt filesystems in my installation. Additionally it is a live ubuntu-mate 15.04 beta2 usb installation with casper-rw file.
Further system informations:

1) ubuntu-mate@ubuntu-mate:~$ lsb_release -rd
Description: Ubuntu Vivid Vervet (development branch)
Release: 15.04

2) ubuntu-mate@ubuntu-mate:~$ apt-cache policy cryptsetup
cryptsetup:
  Εγκατεστημένα: 2:1.6.1-1ubuntu7
  Υποψήφιο: 2:1.6.1-1ubuntu7
  Πίνακας Έκδοσης:
 *** 2:1.6.1-1ubuntu7 0
        500 http://archive.ubuntu.com/ubuntu/ vivid/main i386 Packages
        100 /var/lib/dpkg/status

3)I expected to update initramfs but I suppose it is no possible in a live ubuntu install. Perhaps I'll just uninstall cryptsetup, as I don't use it.

4) The synaptic upgrade procedure couldn't upgrade cryptsetup.
