[Bug 947664] Re: Unpacking linux-headers unbelievably slow in Lubuntu Precise (Beta 1)

[Roger]

I have noticed this issue also S. Christian Collins.
I have an Ubuntu host running Ubuntu Budgie 18.04 with three different VMs - one Ubuntu 16.04, one Ubuntu Budgie 18.04 and one Ubuntu Budgie 19.04 (the last two are running Linux kernel 5.0).
Had no problems with kernel updates until three weeks ago when I had to reinstall the host machine.
After I reinstalled the host with Ubuntu Budgie 18.04.3 (with linux kernel 5.0.0.x) I noticed that the kernel updates became very, very, very slow. I even got warnings about packages broken!
The original installation ran Ubuntu Budgie from release (18.04.01, kernel 4.15).

Also, I noticed that the same Ubuntu Budgie 18.04.03 guest VirtualBox
installation took only 2 minutes to update on Windows 10 host from Linux
kernel 5.0.0.27 to 5.0.0.29.

One other comment is that I am using VirtualBox 6.0.10.

Title:
  Unpacking linux-headers unbelievably slow in Lubuntu Precise (Beta 1)

Status in dpkg:
  New
Status in dpkg package in Ubuntu:
  Fix Released

Bug description:
  The below is an example line in an apt-get dist-upgrade which seems to
  take 30 minutes or more on a 2.1GHz CPU (one core of a quad core
  through Virtualbox). I've been looking at it for ages, and even had
  time to log in here and file the bug  - the line is still 'hung'.

  Unpacking linux-headers-3.2.0-18 (from .../linux-
  headers-3.2.0-18_3.2.0-18.28_all.deb)

  Can anyone explain this, or is it a bug in the configuration of
  Lubuntu, Apt-get or something. I read that there was a similarly
  behaving bug to do with dpkg using paranoid file synchronization but
  this length of delay is frankly a bit crazy.
