Title:
  APT daily cronjobs hangs, prevents other cronjobs to be executed

Status in apt package in Ubuntu:
  Fix Released

Bug description:
  Hi,

  I've created a cronjob in /etc/cron.daily (a very simple mysqldump)
  and have been looking for weeks why it wouldnt execute... Following
  the advice of a friend I run:

  sudo su -
  run-parts --report /etc/cron.daily 

  Which seemed to hang completely. I straced the process, and it seemed it was hanging on the APT cron job; 
  access("/etc/cron.daily/apt", X_OK)     = 0
  pipe([3, 4])                            = 0
  pipe([5, 6])                            = 0
  clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0xb7db86f8) = 13861
  close(4)                                = 0
  close(6)                                = 0
  select(6, [3 5], NULL, NULL, NULL

  I removed the APT cronjob and now the run-parts works fine...  would
  be worth testing but I wonder if all the cronjobs following
  /etc/cron.daily/apt are executed properly...

  Maybe this bug is linked to https://bugs.launchpad.net/ubuntu/+source/apt/+bug/86896 ?
  I am using Jeos 8.04 built with uvb - tell me if I can provide any additional information, thanks!
