[Bug 1008105] Re: "The package lists or status file could not be parsed or opened"

[John Drinkwater]

`apt` needs to be more robust against this kind of breakage. A 3rd party
repo today updated a file which had a broken Depends field, and that
broke update-manager from being usable, and synaptic from getting beyond
the initial loading - it refused to work.

```
john at joran ~/code/UnrealEngine ±:promoted❯ sudo apt install build-essential mono-gmcs mono-xbuild mono-dmcs libmono-corlib4.0-cil libmono-system-data-datasetextensions4.0-cil

Reading package lists... Error!

Bug description:
  Hi,

  My Task bar at the top has a stop sign. An error keeps occurring.

  E:Read error - read (5: Input/output error), E:The package lists or
  status file could not be parsed or opened.

  I am running U12.04     5.2.2

  I am attempting to Update My Software

  The program loads what needs to be updated (currently 165 packages)
  however when I click on Install Updates it fails with the above error
  code.

  And it has requested that I inform a member of the development team.
  So I am.

  Hope this helps you guys :-)

  All the best,

  Adam Carter
