Selective upgrading from hardy-proposed

Create the file /etc/apt/preferences with this content:

Package: *
Pin: release a=hardy-updates
Pin-Priority: 900

Package: *
Pin: release a=hardy-proposed
Pin-Priority: 400

You can then start aptitude to select the -proposed packages you want to upgrade with

sudo aptitude -t hardy-proposed

This means you won't be prompted to upgrade all the -proposed packages, only ones you want to upgrade.

Enable Apport

When running proposed it is recommend that you re-enable Apport bug filing to capture and report crashes. In the event that you end up reporting a crash about a proposed package please tag the bug as proposed-pkg so we can distinguish it from other crash reports.

You can enable Apport on a stable system with:

gconftool -s /apps/update-notifier/show_apport_crashes --type bool true

Hardy also needs Apport to be enabled in /etc/default/apport, edit this file and change enabled to 1.

sudo nano /etc/default/apport

Once Apport is enabled you need to start the process do that with the following command.

sudo /etc/init.d/apport start

To test that Apport is now running, enter the following command to cause a simple crash and generate a crash file in /var/crash:

sh -c 'kill -SEGV $$'

This should notify about the crash and offer you to submit it to Launchpad. Click on 'Report' and verify that the details look complete (package name and version, has a (broken) stack trace, etc.). Please do not actually send it to Launchpad, though, since it is not a genuine bug.
