Be aware of aptdaemon transaction which are running in the background

[QPrime]

Aptdaemon allows to close a client application also if the transaction is still running or queued. Update-notifier should be aware of queued transaction and should allow users to access the background transaction.

To avoid writting a C client for aptdaemon, update-notifier could listen to the ActiveTransactionChanged signal and launch software-center on request.

Furthermore the shutdown dialog should check if there are still running transactions.

Original bug report:

Binary package hint: update-manager

A manually triggered update will sometimes silently update in the background with no interactive feedback. The user is left with a "Waiting for other tasks" dialogue. The update will continue as normal but the user is never informed as to its status. On at least one occasion this has resulted in damaged (but repairable) apt database due to shutdown while an update was taking place.

could you give details on what you would like to see changed in indicator-applet there?

the issue is not an indicator-applet one

I'm trying to triage this bug for Ubuntu Software Center, but I don't understand it fully because there are no steps to reproduce it. Could someone update the description to include those steps? Thanks.

<https://wiki.ubuntu.com/SoftwareCenter#installing> and <https://wiki.ubuntu.com/SoftwareCenter#removing> both say that USC "should begin blocking session exit". (I guess maybe aptdaemon should be responsible for that instead.) Is there anything else USC needs to do to fix this bug?

[Sebastian Heinlein (glatzor)]

Aptdaemon hasn't got any access to the session of the user (by design).

Steps to reproduce:

1. upgrade package using update-manager or installing packages using s-c
2. kill s-c or upgrade-manager during the installation
3. Choose shutdown from the panel
=> broken system

The shutdown menu should not allow to shutdown during a running transaction installation and should cancel queued transactions before shutting down.

Which package provides the shutdown menu in Ubuntu?

its indicator-session

Sebastian, Please could you check if this behaviour is still occurring in latest release included in Ubuntu Maverick?
