wrong bug duplication - ubiquity-dm crashed with ValueError in command(): invalid literal for int() with base 10: ''

installer logs attached. From the logs this would be caused by a X crash. Setting status to triaged/medium.

this bug is very likely related to bug 708744

I experienced this with the iso-testing Alpha 2 i386 build also. It appeared along with bug 702898.

It popped up after ubiquity displayed the Keyboard layout screen.

I've not been able to reproduce this bug with the rebuilt image this AM.

I experienced this too with the Ubuntu Alpha 2 i386 20110202 image + compiz had crashed also on LiveCD.

Same here with Alpha2 amd64 daily-live/20110207

same here using natty alpha2.
at first the installer opens with top panal and indicator applets but no launcher
after 3-4 minutes...a panic screen or text mode black screen cums saying " terminating v " or something
then again new dextop arrives with panal and launcher but installer is not opened by default....

and ya even after this compiz tends to crash some time

my hardware config: amd athlon x2 555 black edition,asus 785td evo motherboard(ati radeon 4200 chipset),2gb ddr3 ram

same here after installing alpha3 in VirtualBox. Install went fine, I have choosed erase and use whole disc during installation.

This ubiquity crash also happened to me while attempting to install 11.04 alpha 3 64 bit (desktop) to a test partition on my hard drive. Please note that 11.04 alpha 2 installed without a problem. I reposting my comments and bug report from Bug #730220.

***************

Binary package hint: ubiquity

Ubiquity crashed during install of Ubuntu 11.04 (Natty Narwhal) alpha 3. Manual partitioning setup to sda2 single partition set as "/" with grub2 installed to sda2 as well (triple boot system with Linux Mint 10's grub2 installed in MBR). This type of install worked with 11.04 alpha 2--no installer crashes. Am not able to install alpha 3 due to Ubiquity crashing during install.

Additional information to initial report: (All 3 install attempts were clean installs)

Attempted installation of 11.04 alpha 3 was to an already created test partition (sda2) which I initially install 11.04 alpha 2 (and other past distros as well). During install of alpha 3 I chose to specify partitions manually and pointed the alpha 3 install to sda2, mounted as "/" and formatted as ext4. The installer (Ubiquity) crashed in the same place during 3 different install attempts; approx. half-way through "Installing system" after all files were copied and all packages were downloaded.

The first install attempt was set to download upgrades and install 3rd party software and not to transfer any data from the 2 other distros I have installed on the same hard drive. Installer crashed.

The 2nd and 3rd install attempt was set to not download any upgrades but to install 3rd party software and to not transfer any data from my other OSs. These are the same settings as I used when I successfully installed alpha 2. Installer crashed the same way each attempt as well.

***************

Update: Downloaded another 11.04 alpha 3 64-bit (desktop) .iso from the main link on the Natty alpha 3 page and burned to CD, md5 checksums match. Installer crashed as initially described in this bug report. Cannot install alpha 3.

***************

As a redundancy check I re-installed alpha 2 using the exact same parameters as I used for alpha 3 above and alpha 2 installed successfully the first time. For both alpha 2 and 3 installation was started when prompted to "Try Ubuntu" or "Install", choosing to install rather than letting the Live session desktop fully load...

With the daily build 2011.03.08 it ends during the installation with 'Scanning the CD-ROM...' and the error message 'An attempt to configure apt to install additional packages from the CD failed'

Getting debconf debug output would help out determining the root cause of this bug. Could someone run the installer with 'ubiquity -d' from a terminal, and post /var/log/syslog and /var/log/installer/debug? This would be a huge help!

I don't agree with Jean-Baptiste's diagnosis of this as an X crash. What happened was that usermod segfaulted:

Oct 1 11:18:54 ubuntu kernel: [ 1201.341294] usermod[7311]: segfault at 10 ip 0804ae0e sp bfa0ed68 error 6 in usermod[8048000+11000]

... and then a chain of stuff fell over. I would tend to pin this on hardware problems

Most of the bugs duplicated against this probably shouldn't be.

I've attempted to arrange for this spurious crash not to happen in future versions (ubiquity >= 2.5.33).

somewhat agree with colin's opinion..though it's still to be verified.

I just used today's posted nightly build of 11.04 and encountered this error. My bug submission was marked as a duplicate, but if this is marked as the fix has been committed, is there some further vetting of that commit before it makes it to the nightly? Just want to make sure everyone is aware it's still an issue, and that if the commit was in the nightly, it did not fix it. That, or my bug submission was incorrectly marked as duplicate.

I'm running into this issue when trying to install from an Ubuntu 11.04 live USB, so as far as I can tell, it isn't fixed in the Natty final release.

Looking at some of the duplicates of this bug report the crash occurred due to faulty media or hardware. You can check your syslog attachment added to your bug report and look for SQUASHFS errors in it. In the event that you find them they are indicative of bad media or a faulty drive. Please try burning the CD at a slower speed or cleaning your media and drive. Thanks and good luck.

You are correct.
The problem was caused by a faulty Ram chip
the ram chip was removed and the problem never ocurred again.

good night

Trying to install 32 bit 11.04 in virtual box on a 32bit windows 7 laptop.

If the issue 864559 which I reported is a duplicate of this, then I am able to reproduce it consistently.

I added an apport task because apport duplicates unrelated issues based on the last ubiquity traceback.

All duplicates have exactly the same stack trace, so I guess if they are unrelated issues we need to look at something else to tell them apart. Colin/Evan, can you please give me some advice what else to look at here? Should this particular crash be ignored in general? Should we look at something in the log file and adjust DuplicateSignature: accordingly, etc.?

Looking at this bug and bug 897270 it seems odd to me that the Traceback.txt doesn't appear in the UbiquitySyslog file at all. Additionally, looking at all the duplicates the latest version of ubiquity that this (the traceback disconnect) happened in was version 2.6.10 from Natty and 2.7.10 which is no longer available. So I'm not certain this really needs fixing anymore.

Having said that the Traceback.txt in this report is very generic and it would be helpful to blacklist it as a duplicate signature if possible.

Status changed to 'Confirmed' because the bug affects multiple users.
