installation hangs on 15reuse w/ blank disk

[Norbert Moldován]

Binary package hint: ubiquity

Installing Natty, but after pressing forward on the Preparing to install Ubuntu window ubiquity lags forever.

The image was right, now I'll try to burn it on another cd and see if that solves this issue.

I'm also affected by this bug ;)

[Mario Limonciello (superm1)]

this is being caused by a problem with partman-auto's new 15reuse method.

Here's a syslog with set -x on all of partman-auto's 15reuse files.

The disk was blank when I started.

Adding a OEM Priority task as I've seen a number of emails related to this today

This bug was fixed in the package partman-auto - 93ubuntu6

---------------
partman-auto (93ubuntu6) natty; urgency=low

  * Don't explode on unpartitioned space in the reuse option (LP:
    #722198).

I'm still seeing problems with this, even with the 2.5.18 ubiquity update from yesterday, which contains the partman-auto fixes.

The installer still gets 'stuck' at any attempts to partition the disk, either automatically or manually.

I've attached the /var/log/installer/debug output and the /var/log/syslog output with 'debug-ubiquity' added to kernel command line.

[Evan (ev)]

Can you attach the output of `ps auxf` when the installer is hanging to this bug? Thanks!

[Kent Baxley (kentb)]

Hi Evan,

Here you go. Let me know if I can get anything else for you. Thanks.

[Kent Baxley (kentb)]

With today's build of Natty, it looks like we're finally good to go. I can partition a blank disk either manually or via auotpartitioning without any hangs.

[Evan (ev)]

Can anyone still reproduce this with the latest daily-live CDs? I believe we took care of this with further changes to partman-auto, but I want to be sure before closing this bug.

[Luke Yelavich (themuso)]

Yes, can reproduce here with a totally blank partition table. Syslog with set -x for 15reuse files attached.

[Bojan Rajkovic (bojanr)]

+1, can reproduce. Trying to install over a Debian install, and I never make it to the partitioning stage. Always stuck at the first page of the wizard. Partman fails with udpkg: not found. /var/log/installer/debug from running ubiquity --debug is attached.

[Bojan Rajkovic (bojanr)]

Also attaching ps auxf output, and the last line in syslog that's relevant is:

Mar 13 19:15:43 ubuntu ubiquity: umount: /tmp/tmp.pHSxYl51qp: not mounted

[Bojan Rajkovic (bojanr)]

Hmm, I think I've found what triggers the bug--partman only freezes if there's unpartitioned space (I had around 280 GB reserved for a Windows 7 partition). After formatting the empty space as NTFS with GParted, I was able to continue with the installation.

[Colin Watson (cjwatson)]

I'm pretty sure that these changes cover the various problems along these lines:

partman-auto (93ubuntu10) natty; urgency=low

  * Guard against blkid returning non-zero (LP: #729394).

ubiquity (2.5.27) natty; urgency=low

  * Drop code related to debian-installer/fallbacklocale, since that
    template no longer exists (LP: #736060).
  * Update imported translations from gtk+2.0 2.24.3-0ubuntu2 and
    gnome-panel 1:2.32.1-0ubuntu6.
  * Ensure that PartedServer dialogs are always properly closed on
    exceptional paths.
  * Fix partition-table-full check to cope with disks without a partition
    table.

 -- Colin Watson <email address hidden> Wed, 16 Mar 2011 14:36:02 +0000

If partitioning still fails with a current daily build, please open a new bug and attach /var/log/syslog, /var/log/partman, and /var/log/installer/debug.
