[Bug 1819438] Re: Install fails on ppc64: partman: *** stack smashing detected ***

[Steve Langasek]

March 5 was the day the glibc 2.29 migration landed in the release
pocket, bringing with it a large number of other dependent packages.
This could be due to version skew of glibc itself between the d-i initrd
and the image, or it could be a regression introduced by some other
package updated in the image (merge of new upstream version partman-base
migrated that day, so it's my second guess).

A rebuild of d-i against current glibc has just landed, so trying an
image respin now to see if this alone is sufficient to fix the problem.

Title:
  Install fails on ppc64: partman: *** stack smashing detected ***

Status in debian-installer package in Ubuntu:
  New

Bug description:
  Since March 6 the installer of the ubuntu-disco-server-ppc64el daily
  images consistently fails. The installer can't pass the "Partition
  disks" stage: the stage fails silently, without showing the classic
  d-i red error screen. A dig in the syslog shows:

  partman: *** stack smashing detected ***: <unknown> terminated
  partman: *** stack smashing detected ***: <unknown> terminated
  partman-lvm: *** stack smashing detected ***: <unknown> terminated
  debconf: --> PROGRESS STEP 1
  debconf: <-- 0 OK
  debconf: --> PROGRESS INFO partman/progress/init/parted
  debconf: <-- 0 OK
  debconf: --> GET partman/alignment
  debconf: <-- 0 optimal
  debconf: --> PROGRESS STOP
  debconf: <-- 0 OK
  main-menu[2181]: (process:10235): *** stack smashing detected ***: <unknown> terminated
  main-menu[2181]: (process:10235): Aborted
  debconf: --> GET debconf/priority
  debconf: <-- 0 critical
  main-menu[2181]: INFO: Menu item 'partman-base' succeeded but requested to be left unconfigured.

  but the step clearly did not succeed. Trying again to perform the
  "Partition disks" step produces more

  main-menu[2181]: (process:10235): *** stack smashing detected ***:
  <unknown> terminated

  errors in the syslog, and indeed this is what happens when trying to
  run partman manually:

  ~ # partman
  *** stack smashing detected ***: <unknown> terminated

  This problem renders the current Ubuntu disco images uninstallable on
  ppc64. Let me know if you need to know any other information to better
  investigate it.
