[Bug 1310592] Re: apt-get doesn't update lists timestamp

[David Kalnischkies]

Well, you should tell us your sources then, otherwise we wouldn't know
how to reproduce. Also, the output of "ls -l /var/lib/apt/lists" to see
the timestamps might be helpful.

Note that apt isn't setting the timestamp to your last execution of apt,
but to the last modification time the server reported. This is needed as
otherwise mirror updates might be hidden due to timing: achieve is
updated, you apt-get update against a mirror, mirror is updated, you
update again: If we updated timestamps to your last apt-get run you
wouldn't get any updates in this situation.

Title:
  apt-get doesn't update lists timestamp

Status in “apt” package in Ubuntu:
  New

Bug description:
  Some APT lists under /var/lib/apt/lists time stamp is not updated when
  running apt-get so every time apt-get downloads them again which
  result in very big download size.

  Doing "touch" to the affect file list solves the problem.
  This is affecting 14.04
