[Bug 1361951] Re: Ubiquity freezes while reformatting occupied partition

[Erick Brunzell]

During Wily final iso testing last night I experienced my first ever
such freeze while reformatting a primary partition as shown in the
attached side-by-side screenshots. I included the gnome-clock at the top
so you can see it's an actual freeze, the first shot was probably 10 to
15 minutes into the process and the next is more than 30 minutes later.

Just to give an idea of how random this freeze may be, I've performed
that identical test on the same partition dozens of times in the past
and this is the first time it's frozen with a primary partition like
that. It's much more likely to occur on a logical partition in the
double digits.

Title:
  Ubiquity freezes while reformatting occupied partition

Status in partman-ext3 package in Ubuntu:
  Triaged

Bug description:
  I'm testing an Ubuntu GNOME Utopic 20140826 i386 image and after
  selecting Something else and creating two partitions on a blank 80 GB
  (primary / about 77500mb and logical swap about 2500mb) shortly after
  the installation begins it freezes with the bottom of the window
  saying, "Creating ext4 filesystem for / in partition #1 of SCSI2
  (0,0,0) (sda) ...........".

  I've repeated this twice just in case the first attempt was a fluke,
  and the first time I waited well over an hour. I'm filing this report
  with the installer seemingly still attempting to run. I'd gladly
  repeat the test choosing to kill the installation before filing if I
  knew how.

  I'm attaching an actual screenshot of what the screen displays while
  frozen.
