[Bug 1396380] Re: Installation stuck on "Preparing to install Ubuntu"

[momiga]

I have the same issue, also installing alongside Windows 7. I did `ps
axjf' and noticed it was stuck running `ntfsresize -f -i /dev/sda2',
which was called by a partman script. I assume the script was trying to
determine the minimum size of the Windows partition to give an option to
resize it. The path to the script on the LiveCD was:

/lib/partman/automatically_partition/10resize_use_free/option

My workaround was the remove the part of the partman script responsible
for calling ntfsresize, since I already had my disks prepartitioned.
Ubiquity worked fine after that, and it was able to automatically
install alongside Windows 7.

I'm probably going to post about this in the Ubiquity package bug
tracker. ntfsresize is really slow on real world NTFS file systems and
shouldn't be being used by Ubiquity in such a way unless requested by
the user.

Title:
  Installation stuck on "Preparing to install Ubuntu"

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:

  - With ubuntu 14.10 Desktop 64-bit already installed, try ro re-install it (from USB stick)
  - Choose the language (English), continue and tick the two checkboxes (download updates while installing and install the 3rd party software), continue
  - it remains there indefinitely, with the "wait" cursor

  (I hit Ctrl+Alt+F1 to login and submit the bug report)

  What I have tried to fix the issue:
  - Because it was a re-installation in a dual boot configuration with Windows 7, I booted Windows 7 and  from Windows deleted the two volumes previously used by Ubuntu (/ and swap), and tried again to install ubuntu, reproducing the same issue as before.
  - Started ubuntu from the USB stick (without installation) and formatted the now free space on disk as two ubuntu partitions (approx 40 GB and 8 GB respectively); then tried ubuntu installation again, reproducing the same issue as before.

  Workaround:
  -  unchecked download updates while installing and install the 3rd party software, and installation continued correctly.

  I am attaching a /var/log/syslog collected after reproducing the issue
  and before reboot, but I can find no /var/log/partman.
