[SRU] Click on the back icon in gnome-software doesn't work

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:
http://iso.qa.ubuntu.com/qatracker/reports/bugs/1798053

I see this also in a live Ubuntu Studio session. I installed AnimationMaker (snap). The install button stays active after installation. I ran the Animation app from the menu - all worked fine. Going back to Gnome Software, the Back button does nothing. All other buttons and menu icons work, including the Install button (which should not really be active - it does give a "this app is already installed" error message when clicked though).

Today (after previous ISO rebuild), gnome-software allowed me to install a snap (picard this time), and after installation the buttons changed to launch, remove etc. I was able to launch the application, and after I quit it, the back button in gnome-software took me to the front page.

Either it was a glitch, or something was fixed for this release candidate.

Checking the gnome-software version on today's ISO, it did change, and is at 3.30.2-0ubuntu4. I can't tell from the changelog, or patch description in the new version, if it was the change that fixed it.

This is not fixed, I can still reproduce the issue by opening the details page for any app (snap or deb, installed or not), then closing gnome-software, then opening it again.

Confirmed issue, with all available updates. Cannot press back button in Ubuntu Software. Closing and reopening software does not fix the issue until a reboot is performed.

Killing the gnome-software process fixes the issue without the need of rebooting.

I'm seeing the following error in the logs when clicking the back button without effect:

    Gs gs_shell_go_back: assertion '!g_queue_is_empty (priv->back_entry_stack)' failed

Upstream bug report: https://gitlab.gnome.org/GNOME/gnome-software/issues/505. This is supposedly fixed in gnome-software 3.30.3, but I'm not sure which commit is relevant.

The relevant commit is https://gitlab.gnome.org/GNOME/gnome-software/commit/ca5f8e74b6f9991ae228caa2c698131a54764774, and I verified that applying it as a patch on top of gnome-software 3.30.2-0ubuntu7 fixes the issue. In fact, with this change, when re-opening gnome-software after closing it while seeing the details of an app, the application is reset to the main screen. Which may or may not be seen as desirable, but at least it fixes the bug.

Cherry-picked upstream fix: https://git.launchpad.net/~ubuntu-desktop/ubuntu/+source/gnome-software/commit/?id=1bca94696815b2ead57a4a27df87131a3cb9995e

Hello Per-Inge, or anyone else affected,

Accepted gnome-software into cosmic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gnome-software/3.30.2-0ubuntu8 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 on 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-cosmic to verification-done-cosmic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-cosmic. In either case, without details of your testing we will not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Tested and behaves as expected. When gnome-software is started again the
home screen is shown.

Negativo Per-Inge (per-inge-hallin)

Abra qualquer aplicativo na loja e feche a loja. Em seguida, abra de novo pra ver se o ícone de voltar a página e verás que não retorna a página inicial. Simplesmente trava.

Acabei de testar novamente e o problema persiste.

Negative Per-Inge (per-inge-hallin)

Open any application in the store and close the store. Then open it again to see if the icon returns to the page and you will see that it does not return the homepage. It just hangs.

I just tested again and the problem persists.

To get the new version of ubuntu/gnome-software you have to enable
"Pre-released updates" in "Developer Options" and allow all updates of
ubuntu-software.

Thanks for testing and the feedback Per-Inge. I am seeing the same with the update in cosmic-proposed. I suspect Edson either didn't really install the update, or didn't restart gnome-software after installing it. Let's wait and see whether he can confirm.

Thanks Edson. As I suspected, you didn't really install the update from cosmic-proposed. If you wish to do that, you will need to follow the instructions at https://wiki.ubuntu.com/Testing/EnableProposed, and then ensure that the version of gnome-software installed is 3.30.2-0ubuntu8.

Tested in an up-to-date amd64 cosmic VM with cosmic-proposed, and version 3.30.2-0ubuntu8 of gnome-software. Verified that the fix works as advertised.

Just for anyone like me finding the bug by search, the man page notes you can open gnome-software to a particular screen which works around being stuck on the last one accessed, eg:

gnome-software overview &

The easiest workaround I found is to close it, then right-click the icon
and select "view details". I have no idea what that is supposed to do but
for some reason it opens the software centre on the updates tab, or
something like that.

When will the bug fix be released to users?

gnome-software 3.30.2-0ubuntu8 should have made its way to cosmic-updates already, not sure why it hasn't yet.

@Olivier - comment #31 was really about the bug being fixed in disco, its just that the package and subsequently the changelog was copied from cosmic.

The verification of the Stable Release Update for gnome-software 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 regressions.

 -- Olivier Tilloy <email address hidden> Tue, 23 Oct 2018 17:13:49 +0200

As a part of the Stable Release Updates quality process a search for Launchpad bug reports using the version of gnome-software from cosmic-proposed was performed and bug 1800286 was found. Please investigate this bug report to ensure that a regression will not be created by this SRU. In the event that this is not a regression remove the "verification-failed-cosmic" tag from this bug report and add the tag "bot-stop-nagging" to bug 1800286 (not this bug). Thanks!

Bug #1800286 is very unlikely to be caused by this SRU.

Any update on this issue? It's 2 months later and my fresh ubuntu 18.10 installation is failing on this. Whenever I close the app on a specific page, it never wants to go back. Imagine a new user using Ubuntu for the first time, this leaves a _very_ bad impression

Linaori: the fix was released with an update on 2018-11-05.
Can you please check that your system is fully up-to-date? The version of gnome-software should be 3.30.2-0ubuntu8.
