ubiquity in precise-updates, doesn't have tight enough dependency on python-apt leading to crashers

[Matthew J. Fitzpatrick]

ubiquity in precise-updates should have a tighter dependency on python-apt, specifically >= 0.8.3ubuntu7.2 as it depends on functionality provided by that python-apt SRU.

This bug affects only out-of-date live precise installation media, where users choose to upgrade live ubiquity.

WORKAROUND:

Boot and choose try Ubuntu. Then run 'sudo apt-get update', 'sudo apt-get install python-apt' in a terminal, before starting ubiquity.

Alternatively use a 12.04.4 install media if one is available for your derivative e.g. mythbuntu, lubuntu, ubuntu-studio.

original report
---------------
I booted off of MythBuntu LiveCD to install on HDD. I selected all options for remote access, all add-ons and third party repositories, and option for Remote Control via Hauppauge TV Card (I know the Hauppauge WinTV-HVR-2250 is supported but it's not yet available in the drop-down list so I selected generic Hauppauge TV Card option). About 10 minutes into the install it just crashes with the same thing each time. I also tried rebooting computer and trying install process again.

I suspect that ubiquity is getting updated and it then needs the latest version of python-apt which is not installed. See further the fix for bug 1051935.

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

[Brian Murray (brian-murray)]

Hello Matthew, or anyone else affected,

Accepted ubiquity into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/ubiquity/2.10.30 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Brian Murray (brian-murray)]

This fix seems incomplete to me as ubiquity only build-depends on the new version of python-apt and when running a 12.04.3 live image if you install ubiquity version 2.10.30 from precise-proposed, the new version of python-apt is not installed. See also:

The version of ubiquity in the proposed pocket of Precise that was purported to fix this bug report has been removed because the bugs that were to be fixed by the upload were not verified in a timely (105 days) fashion.

[Steve Langasek (vorlon)]

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
