[Bug 1500110] Re: mount point /tmp/tmp.${RANDOM}/var does not exist

[TJ]

Another run with 15.10 ubiquity --debub, with "set -x" added to /bin
/partman-commit. Shell script output is captured in var/log/syslog.

This appears to suggest 01apt_clone_save is being called too early -
before the sub-mounts and basic file-system structure is in place maybe?

Title:
  mount point /tmp/tmp.${RANDOM}/var does not exist

Status in ubiquity package in Ubuntu:
  New

Bug description:
  ubiquity 2.21.31

  mount point /tmp/tmp.${RANDOM}/var does not exist

  Running the manual partitioner on 15.10 kubuntu desktop amd64 for
  2015-09-24 this error shows up in the syslog after assigning existing
  (empty) ext4 LVs for root-fs /home /var /usr/local (no swap assigned)
  and /dev/mapper/LUKS_BOOT for /boot (LUKS /dev/sdc4).

  The ubiquity process then spins at close to 100% of 1 CPU, shows
  "Saving installed packages... 0%", slide-show continues but
  /var/log/syslog doesn't show any progress.

  ubiquity 2.18.8.9 on 14.04 is also affected in an identical way.
