[Lucid] ubiquity crashed with , E in update() when I clicked on "update this installer"

[Charlie Kravetz]

Binary package hint: ubiquity

RELEASE: Lucid Lynx development version
CD/DVD VARIANT: all desktop images
ISO BUILD: 2010-03-06
SYMPTOMS:
    Preparing to install using the live environment desktop launcher. When Ubiquity starts, the first page is Welcome. If I click on "update this installer" without an internet connection, ubiquity errors with this report. Further, the installer is now showing "Checking for installer updates" , frozen at 60% on the progress indicator, file 62 of 100. There is no way to continue this update, even after creating the internet connection.

    The only way to close the updater now is right-click on the bottom panel, "Checking for installer...." , left-click close.

    I would have expected to at least get an error message that there is no network connection instead of an apport report. There should be a check built in to throw an error screen up that there is no connection before the installer even attempts to get any updates.

    The only way I found how to close the indicator is experience. The new user would have been completely lost and be forced to restart the machine with a hard power off.

STEPS TO PRODUCE:
    1. From the desktop cd menu, select "Try without installing".
    2. After the desktop appears (about 15 minutes on my 1.5GHz, 1GB ram system), click the icon to install.
    3. Make sure there is no internet connection. I use static IP' s only, and forgot to set it up.
    4. Read the 'Welcome' screen, and click on "update this installer" in the last sentence.
    5. Observe the installer checking for updates.
    6. It will give an apport error and freeze the indicator.

The same crash occurs (for me repeatedly at 24%) if you install direct from the Live CD without trying Ubuntu first. If you have wireless internet only, obviously it won't be configured at installation time so Ubiquity hangs after user selects 'Update this installer'.

Is it possible for Ubiquity to check if an active internet connection is available and if not, hide the 'Update this installer' button?

It does work over wifi however, if you run the live CD, configure the wifi and then choose to install permanently afterwards.

I should mention, if you start the installation without trying first, I didn't get an Apport report; it just hangs.
