Comment 7 for bug 158178

This error continues even with later versions of at, on every upgrade (not just installation); I've just verified it with 3.1.10.2ubuntu2, and an x86 version (on jaunty-proposed):

Setting up at (3.1.10.2ubuntu2) ...
 * Starting deferred execution scheduler atd invoke-rc.d: initscript atd, action "start" failed.
dpkg: error processing at (--configure):
 subprocess post-installation script returned error exit status 1

However, the bug I've seen here might be bug #281672 rather than this one; it's even possible that the two are the same bug. I'm re-opening this per instructions; but it may be worth marking this bug as a duplicate of #281672 if they are indeed the same bug (it's similar symptoms and similar triggers, although of course that doesn't mean they're the same).
