Description Adam Williamson 2023-05-12 21:14:57 UTC

In today's Fedora Rawhide compose (Fedora-Rawhide-20230512.n.0), anaconda's help doesn't work. Clicking a Help button in anaconda doesn't seem to do anything.

Reproducible: Always

Steps to Reproduce:
1. Download https://kojipkgs.fedoraproject.org/compose/rawhide/Fedora-Rawhide-20230512.n.0/compose/Everything/x86_64/iso/Fedora-Everything-netinst-x86_64-Rawhide-20230512.n.0.iso
2. Boot it
3. Hit the Help button
Actual Results:  
Nothing appears

Expected Results:  
The help should appear (in yelp)

In the journal, this error appears when the help button is clicked:

at-spi-bus-laun[pid]: g_dbus_method_invocation_return_dbus_error: assertion 'error_mesage != NULL' failed

and at-spi2-core changed in the affected compose (from at-spi2-core-2.48.0-1.fc39 to at-spi2-core-2.48.1-1.fc39), so I'm filing against at-spi2-core initially. anaconda and yelp did not change in the affected compose. CCing the anaconda devs for info.

Proposing as an F39 Final blocker per "Any element in the installer interface(s) which is clearly intended to display 'help' text must do so correctly when activated." - https://fedoraproject.org/wiki/Fedora_39_Final_Release_Criteria#Installer_help

Oh, this is only broken in traditional installer images - netinst, server DVD, silverblue installer. It works OK on live images (KDE and GNOME).

Comment 2 Adam Williamson 2023-05-12 21:28:26 UTC

Whoops - turns out I just didn't wait long enough. yelp does *eventually* launch, after 56 seconds.

Comment 4 Adam Williamson 2023-05-12 21:39:00 UTC

So, I think the blivet-gui issue is probably the same thing, and there's (at least) a third affected case: nm-connection-editor (which can be launched from the Network & Host Name spoke. All three do eventually run, but take much longer to start than before. So for now I'm gonna figure these are all the same case, and it's *maybe* caused by at-spi2-core. I'll see if I can spin up a Rawhide image with at-spi2-core downgraded and confirm if that's the cause.

Comment 5 Adam Williamson 2023-05-12 21:52:59 UTC

Ah - this may well be https://gitlab.gnome.org/GNOME/at-spi2-core/-/issues/115 , which should be fixed in 2.48.2. We've built 2.48.2 already but it didn't make the compose. I'll grab the image openQA built with that at-spi2-core in it and see if this is fixed.

Comment 6 Adam Williamson 2023-05-12 22:11:12 UTC

Hah, yes, that *does* fix it. Sorry for the noise. So this'll be fine in tomorrow's compose.
