update-manager popup is shown on launcher and alt-tab list but window doesn't show up

[Timo Aaltonen]

Yesterday I got a "popup" from update-manager that shows on the launcher how many updated packages there are available, but left-clicking the icon didn't show the window. Alt-tabbing didn't help either, so I closed it from the right-click menu and the next time it showed I did get a proper popup window.

Today this happened again, so filing a bug now.

Steps to reproduce, hastily written:

0. (create another user account)
1. login to my main account
2. lock screen
3. switch user
4. update package lists
5. switch back to main user

Update-manager window is shown in Launcher and Alt-Tab, but does not appear when selected, by either means.

Closing update-manager from the quicklist, and restarting, makes a visible window, as we've said. Also, starting the upgrade from the quicklist worked, and the in-progress dialog appeared normally. BUT, when the upgrade was done, and should return to the main window, that window was still inaccessible.

I don't know if the two-session scenario is the only way this bug shows up, currently. I used to have this problem, under Precise, with only one user session. But I haven't seen that behaviour in a while.

[Test Case]
0. (create another user account)
1. login to my main account
2. lock screen
3. switch user
4. update package lists
5. switch back to main user
6. Update-manger should be shown in the Launcher
7. Make sure that clicking update-manager icon correctly raise and focus the update-manager window.

[Potential Regression]
None.

[Timo Aaltonen (tjaalton)]

note that the session has been running since Apr 18th, so in case there were relevant updates since, I'll start with a fresh session and try to reproduce.

[Sebastien Bacher (seb128)]

Thanks, that's not the first time I see such issues (my old laptop on precise do it sometime for im clients as well), it seems like compiz doesn't like things starting minimized

[Sebastien Bacher (seb128)]

It would be good to try on an uptodate restarted session, but it's quite an issue if it means users can't access to stable or security updates

[Launchpad Janitor (janitor)]

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

[Jens Wienstroer (jens-wienstroer)]

I also faced this issue frequently in Ubuntu 11.10. Interestingly, the bug does not
show up every time the update manager window pops up in launcher. Two out of
three times the update manager window shows up, when I click the icon.

I hoped this would be solved in Ubuntu 12.04 but the problem is still there.
(I'm having it right now.)

[Edward Donovan (edward.donovan)]

I don't have careful data. But running Quantal, I don't recall seeing this in a while. Problems with focus when the window.is raised, but not with the update-manager window being lost and inaccessible.

Of course, none of us have found a way to consistently reproduce it, so I can't make strong claims one way or the other. But I'll try to keep an eye on it. Thanks.

[Timo Aaltonen (tjaalton)]

I think it's related to me having two sessions on the same computer (mine and my wife's). Not sure but it's possible I see this only when I come back to my session, and update-manager has been run while on the other session.

[Edward Donovan (edward.donovan)]

Ah, that's interesting. It used to happen to me with only one session, and one user account on the machine. Maybe I'll get a chance to test the two-session scenario. Thanks.

[Edward Donovan (edward.donovan)]

Timo, I see what you mean! :) I was able to reproduce what you're talking about.

Steps to reproduce, hastily written:

0. (create another user account)
1. login to my main account
2. lock screen
3. switch user
4. update package lists
5. switch back to main user

Update-manager window is shown in Launcher and Alt-Tab, but does not appear when selected, by either means.

Closing update-manager from the quicklist, and restarting, makes a visible window, as we've said. Also, starting the upgrade from the quicklist worked, and the in-progress dialog appeared normally. BUT, when the upgrade was done, and should return to the main window, that window was still inaccessible.

I guess I'll paste this into the main description.

[Edward Donovan (edward.donovan)]

I just experienced this in Raring. Only one X session running, so it didn't need that two-user scenario.

In this case, choosing Quit from the quicklist is having no effect. The update-manager process remains, and the Launcher and the alt-tab switcher still act as if there's an open window.

I notice now that window isn't attached to any of the virtual desktops. Maybe that's been true all along, and I've just realized it. I have the standard four virtual desktops, and on all of them, the Launcher shows the hollow or outline pip for "open, but not on this desktop."

Similarly, on all of the desktops, plain alt-tab doesn't show update-manager among the open windows. But Control-alt-tab, showing windows from all desktops, always includes it. Selecting it from this list has no effect, just like selecting it from the Launcher. Hm.

[Edward Donovan (edward.donovan)]

For the heck of it, I increased the number of workspaces to 3x3, in a session where this bug had occured, and Unity believed update-manager was open, but not assigned to any of the workspaces. It was not hiding on any of the extra workspaces.

[Karma Dorje (taaroa)]

This affects me too after yesterday's updates.

$ lsb_release -rd
Description: Ubuntu Raring Ringtail (development branch)
Release: 13.04

$ unity --version
unity 6.6.0

[BertN45 (lammert-nijhof)]

Same problem almost directly after loading the system 13.04. This time the Software Updater also stalled as shown in the screenshot, maybe because of the "ubuntu-bug" run? See also bug 1090414.

I could start the Software Updater using the Dash and it stalled at the grub-pc. After reboot and dpkg reconfigure everything was OK again.

[Josh (majik)]

Confirmed on 12.04.

Switching users is not necessary to replicate.

It seems to happen if the Update Manager starts when the screen is locked.

I filed Bug 1092597 which is a duplicate of this one and was marked as such.

[Alberto Salvia Novella (es20490446e)]

Since this bug:

- Is valid.
- Is well described.
- Is reported in the upstream project.
- Is ready to be worked on by a developer.

It's already triaged.

[Maarten Winter (winter-maarten)]

This still happens on Ubuntu 13.10 (64 bit)

Curiously, I don't recall this happening on 13.04 or earlier.

[Leo B. (fuzzbuntu)]

I am observing this bug since 13.04. If I start update-manger via a python debugger (pdb), it works and shows its windows properly, although it's slow as hell. If started normally, it doesn't show its window no matter if it has started automatically or manually. A similar bug seems to affect automated starts of deja-dup since 13.10.

[Colan Schwartz (colan)]

This looks like a duplicate of bug #1003950, but that one has been "fixed", and this is still an issue so I'm not marking it as such. Let's do any remaining work in here to have this really fixed.

[Benjamin Schmid (benbuntu)]

Having this issue frequently also on trusty. I'm a single-session user, but my user session runs for weeks. 2 monitor setup if that matters. I have to close & manually reopen on nearly every instance. Annoying.

[Niklas Wenzel (nikwen)]

I can confirm that this happens when the screen is locked.

[Christopher Townsend (townsend)]

This is actually a Unity issue in how it handles the unmapped Software Updater window. I'm able to reproduce the issue using the instructions in https://bugs.launchpad.net/compiz/+bug/1003950/comments/87.

I think I have a fix and will propose the solution very soon.

[Josh (majik)]

Wow, this semi-critical bug only took two years to be acknowledged by someone who can execute on it!

That's got to be a record for Ubuntu.

[Timo Aaltonen (tjaalton)]

critical? hardly..

great to see it fixed!
