Comment 12 for bug 652916

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. One difference I noticed right off was when the "Try" or "Install"prompt came up the upper "panel" was fully loaded in alpha 2 and was not loaded at all in alpha 3.

I've downloaded alpha 3 .iso twice now from the second link from the top of the "Ubuntu 11.04 (Natty Narwhal) Alpha 3" page under the "Desktop CD" section: http://cdimage.ubuntu.com/releases/natty/alpha-3/

Note: I had attempted to post the /var/crash/"ubiquity crash log" with the initial bug report but the live session wouldn't submit it and the log was no longer there when I checked the above directory from one of my other installed distros (Linux Mint Debian).
