Description Paul Whalen 2013-12-03 19:01:13 UTC 
Description of problem:
Interactive install of F20-TC4 is terminated after selecting 'Text' install. 

Version-Release number of selected component (if applicable):
anaconda-20.25.13-1.fc20

How reproducible:
Everytime

Steps to Reproduce:
1. Perform a text-based network installation on ARM using QEMU or real hardware
2. Select the 'Text' option. 


Actual results:
Install is terminated with the following traceback:

Error in sys.excepthook:

  File "/usr/lib/python2.7/site-packages/gi/module.py", line 104, in get_interfaces_for_object
    interfaces.append(getattr(module, name))

Expected results:
Interactive text installation. 

Additional info:
Selecting VNC option working as expected.
Comment 1 Adam Williamson 2013-12-04 01:36:10 UTC 
From IRC earlier today:

<adamw> oh hey so if you folks didn't see yet, new blocker in tc4, according to pwhalen, text install doesn't work: https://bugzilla.redhat.com/show_bug.cgi?id=1037767
<bcl> mkolman already has a fix for it.

so I'll set this to POST.
Comment 2 lnie 2013-12-04 06:36:38 UTC 
also see this with x86_64(TC4)
Comment 3 David Shea 2013-12-04 15:19:01 UTC 
The text install not working is a dupe of bug 1037626. That bug doesn't mention the issue of python-meh falling over on Gtk stuff (which probably also already has a bug, but I don't know which), so I don't know how you want to track this particular bug.
Comment 4 Adam Williamson 2013-12-04 17:25:24 UTC 
Sorry, c#1 applied to 1037626, not this bug. That bug is the bug for text install not working. This covers a further problem when you hit any crash in text install on ARM: the crash reporter crashes. I think we used to have this on x86 too but fixed it...
Comment 5 Mike Ruckman 2013-12-04 17:31:42 UTC 
Discussed in 2013-12-04 Blocker Review Meeting [1]. Voted an AcceptedBlocker. Reporting failures on ARM violates the alpha criterion: "The installer must be able to report failures to Bugzilla, with appropriate information included." [2]

Does the fix for bug 1037626 also fix this? Try this updates.img

Comment 7 Vratislav Podzimek 2013-12-05 00:32:08 UTC 
The general issue can be tested by switching to the tty2 or second tmux window and sending USR1 signal to the anaconda process (first command in the bash history). That should trigger exception handling which should work properly on every architecture.

From the traceback I can see quite a big issue -- it seems like it's no longer possible to import the Gtk module without the X server running which is quite a big regression in the Gtk. Anaconda tries to import and initialize Gtk to find out if it can run the GUI handler or TUI handler. If the import itself fails, there's nothing that can be done on the Anaconda's side.

If the traceback appears, please try to run python session on tty2 or the second tmux window and enter 'from gi.repository import Gtk' in it. If that raises an exception, please reassing this bug to Gtk.
Comment 8 Mathieu Bridon 2013-12-05 08:39:41 UTC 
I don't think that's a regression in Gtk.

In the old days, you already couldn't import pygtk if you didn't have a running X server, see bug 208608.

Comment 11 Adam Williamson 2013-12-05 18:50:00 UTC 
bcl: I'm not sure that was right. This bug appears to be a breakdown inside python-meh. So yes, the update fixes text installs, and so pwhalen didn't see this bug - but that's because he didn't hit a crash. The correct check for whether this bug is fixed is not 'does text install now work?' but 'if you hit a crasher bug in the installer, do you hit this bug when you try to report it?'

IMBW, but that's what I got from the comments.

Yeah, but that was terrible behaviour that was fixed some time ago in the Gtk.py GI overrides. If it is now misbehaving again, it is a regression. Also if it appears only on ARM (text mode exception handling should be tested regurarly), it is quite a big deal.
