Bug Description

Ubuntu 12.04
USC 5.2

1. Launch the current Ubuntu Software Center in Precise.
2. Click the "Installed" toolbar button to access the list of installed applications.
3. Choose an installed application to remove (choose one for which there is a corresponding icon in the Unity launcher).
4. Click the "More Info" button.
5. In the details view for the application, click the "Remove" button and enter the password for the remove if prompted.
6. The uninstall process begins and the progress bar moves in Software Center.
7. At the end of the install process, verify that the corresponding icon in the Unity launcher has *not" been removed.
8. Close Ubuntu Software Center.
9. Update to both the software-center *and* unity packages in precise-proposed.
10. Repeat steps 1 through 6.
11. This time, at the end of the install process, verify that the corresponding icon in the Unity launcher is *removed*.

Risk of regression is very low as this is fixed by the new add-to-launcher timing from Software Center, and the code in Unity is unchanged for this (see comment #4 for this bug). Just verifying that the correct icon is actually removed should be enough.


Steps to reproduce:
1. Start USC
2. Select a program to install
3. Click “Install”
(in this moment icon of the program flies to Launcher)
4. Enter your password to authenticate
5. After the program is installed click “Remove” to uninstall the program

What happen:
Icon stays in Launcher

Expected results:
Icon of the program disappears from Launcher

This is a fairly recent regression in behavior as the automatic removal of the Unity launcher item after removal of the application has been working and in place in Unity for a couple of cycles now.

As there is no interaction with Software Center for this, I will change the target package for this one to Unity as the regression appears to have happened there.

Many thanks!

While working on a fix in Software Center for bug 925014, I discovered that the root cause of *this* bug appears to be bug 999427, that is, that the Unity launcher items are pointing incorrectly to the desktop files that are installed by app-install-data rather than to the actual installed desktop files. Please see bug 999427 for more details.

The attached branch, lp:~gary-lasker/software-center/unity-launcher-integration-fixes, changes the operation of Software Center to fire the Unity launcher dbus event at the end of the package install process, thereby allowing the values sent over dbus to include the actual installed desktop file path. With this, the launcher icons are now correctly removed when the corresponding package is removed.

With the new add-to-launcher timing from Software Center, no fix is needed on the Unity side so I've set that task as invalid.

Hello mmiicc, or anyone else affected,

Accepted software-center into precise-proposed. The package will build now and be available at in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See 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 change the bug tag from verification-needed to verification-done. If it does not, 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 . Thank you in advance!

I have verified that software-center version 5.2.5 in precise-proposed fixes this bug per the test case given in the description.


tags: added: verification-done
removed: verification-needed

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
