[Bug 1784796] Re: apt update fails - 'std::runtime_error' what(): random_device::__x86_rdrand(void)

[Julian Andres Klode]

This should really only be an issue early during boot, or if you require
a lot of randomness. So I guess wait, use your keyboard a lot, generate
a lot of network traffic? Or manually inject randomness? I don't really
know, and it's out of scope for the bug report to discuss this - you
might want to ask in one of the user support channels (forums, irc,
mailing lists).

Title:
  apt update fails - 'std::runtime_error' what():
  random_device::__x86_rdrand(void)

Status in apt package in Ubuntu:
  Fix Released

Bug description:
  I am seeing the following error randomly on issuing sudo apt update:

   Get:3 http://archive.ubuntu.com/ubuntu bionic-updates InRelease [65.4 kB]
   0% [1 InRelease gpgv 69.9 kB] [3 InRelease 7,779 B/65.4 kB  12%]terminate called after throwing an instance of 'std::runtime_error'
     what():  random_device::__x86_rdrand(void)
   Aborted

  Once this occurs, it normally takes at least one, but frequently more
  than one reboot to resolve. It only happens on one of my systems - a
  self-build server based on Asrock Rack motherboard C3758D4I-4L running
  Ubuntu server.

  I've observed the same issue on the same hardware with the Ubuntu
  18.04.1 live ISO. I'm booting in Legacy mode.
