Comment 15 for bug 1452238

ifupdown depends on initscripts
initscripts depends on upstart
upstart depends on initscripts and ifupdown

The error messages stats that

"dependency problems prevent configuration of ifupdown:
 ifupdown depends on initscripts (>= 2.88dsf-25); however:
  Package initscripts is not configured yet."

Upstart try to pull in ifupdown and initscripts, however, initscripts is already half-installed (because of other depenency), and ifupdown claim it depends on initscripts, so the apt broke at that stage.

I think if we set initscripts as ifupdown's pre-depends, it could solve the problem.

I'll try to verify this solution.
