[Bug 1351404] Re: Installing updates freezes while setting up grub-pc

[Stephen D Metcalfe]

I am a software developer and have this problem on multiple machines.
Update freezes at "Setting up grub-pc (2.02~beta2-9ubuntu1.1)". The
window goes grey and does not continue even if left overnight. Each
machine is an x86 and has multiple disks with versions of Ubuntu
installed (12.04/14.04 32/64 bit). The version most affected seems to be
14.04 64 bit.

Title:
  Installing updates freezes while setting up grub-pc

Status in update-manager package in Ubuntu:
  Confirmed

Bug description:
  I'm installing updates for the last couple of weeks on a virtual machine running under VirtualBox. It got to Setting up grub-pc (2.02-beta2-9ubuntu1)... then it stayed there for 25 minutes before I shut down the virtual box and restored a snapshot.
  Running top shows me that aptd is running at about 25% CPU on a 4 CPU virtual machine.
