[navgust]

Upgrading from 15.10 to 16.04.1: my last messages on the terminal is:
<code>

After that the upgrade hangs, I am still investigating&trying to finish it.

Title:
  File descriptors leaked on lvs invocation

Status in grub2 package in Ubuntu:
  Triaged

Bug description:
  While upgrading to Kubuntu 14.04 yesterday, I got the following error
  messages over and over again:

  Generating grub configuration file ...^M
  File descriptor 3 (pipe:[4852522]) leaked on vgs invocation. Parent PID 6438: grub-probe^M
  File descriptor 59 (/var/log/dist-upgrade/apt.log) leaked on vgs invocation. Parent PID 6438: grub-probe^M

  
  The file descriptors appeared random, and the "Parent PID" was either /bin/sh, grub-install, grub-probe or /usr/sbin/grub-probe:
  grep leaked ./dist-upgrade/apt-term.log |sed 's/.*Parent PID [0-9]*: //' | sort  | uniq -c
       53 /bin/sh
       72 grub-install
      106 grub-probe
     1484 /usr/sbin/grub-probe
