** Also affects: apt (Debian)
   Importance: Undecided
       Status: New

** Description changed:

+ Note:
+ Confirmed on Ubuntu utopic with apt 1.0.9.2ubuntu2

+ Behavior NOT seen on Ubuntu precise with apt 0.8.16~exp12ubuntu10.22

  apt-key export is not case-sensitive to the hex keyid specified.
  Inconsistently, apt-key del is case-sensitive and won't match unless the
  hex keyid is uppercase. This is highly exacerbated by bug #1256565 which
  results in "OK" being printed and success being returned when apt-key
  del doesn't match anything.
  
  The user is reasonably left to conclude that the key has been deleted
  from the trusted keyring when it has not.
  
  Example:
  
  # apt-key export 7fac5991
