[Bug 1429756] Re: FTBFS: test_job_process fails in majority of cases

[James Hunt]

mk-sbuild now fails with a different error:

Setting up udev (219-4ubuntu3) ...
A chroot environment has been detected, udev not started.
/var/lib/dpkg/info/udev.postinst: 35: /var/lib/dpkg/info/udev.postinst: update-initramfs: not found
dpkg: error processing package udev (--configure):
 subprocess installed post-installation script returned error exit status 127
Errors were encountered while processing:
 udev
E: Sub-process /usr/bin/dpkg returned an error code (1)

But back to the test failure... this  test has been running successfully
on all platforms for a long time (3+ years). It's possible that the test
itself is racy and that a recent change in a different package has
exposed that. Do we know when this test first started failing (and
ideally what changes triggered it (kernel/libc))?

  Sometimes they succeed on one architecture, and with lots of luck on
  both, but this is way too flaky to be an useful test. This keeps
  blocking the propagation of other packages from -proposed.
