Title:
  After Plasma 5.5.3 - apt-check causes massive load / creates 100's of
  processes

Status in update-notifier package in Ubuntu:
  Confirmed

Bug description:
  Since upgrading to Plasma 5.5.3 (via 15.10 backports PPA) every
  morning my machine is unusable.

  This morning the load was over 100 on my desktop - there were hundreds
  of apt-check processes, plasma had completely crashed bar one konsole
  window.

  I have to sysRq to reboot...

  Looks like others are having similar issues
