Title:
  apt updates fail with invalid argument

Status in “apt” package in Ubuntu:
  New

Bug description:
  Every apt-get install or upgrade fails with a similar error, only the
  package name differs.  In the below example, I'm trying to update apt
  with the recommended update.  "apt-get upgrade" emits a similar error,
  although for the first package which it selects.

  
  $ sudo apt-get install apt
