Title:
  apt-check uses too much resources (starts too many processes)

Status in “update-notifier” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: update-notifier

  I have quite a few entries in my apt sources. The problem with that is
  that it seems like apt-check is triggered for every one of them, which
  is esp. an issue on slow systems as my EeePC where I end up with 22
  apt-check processes, each one taking up to 50MB of memory, so every
  apt-get update run takes over 1GB RAM to complete. Can't apt-check run
  only once after apt-get update completes? Or at least run them
  sequentially, not in parallel?

  ps auxw | grep apt-check: (after letting it run for a while)
