Text install : Error in sys.excepthook
Last modified: 2013-12-10 01:53:38 EST
Description of problem:
Interactive install of F20-TC4 is terminated after selecting 'Text' install.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Perform a text-based network installation on ARM using QEMU or real hardware
2. Select the 'Text' option.
Install is terminated with the following traceback:
Error in sys.excepthook:

Interactive text installation.
Selecting VNC option working as expected.
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.
also see this with x86_64(TC4)
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.
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...
Discussed in 2013-12-04 Blocker Review Meeting . 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." 
Does the fix for bug 1037626 also fix this? Try this updates.img
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.
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.

Text installs are now working again using the updates.img
anaconda-20.25.14-1.fc20, python-blivet-0.23.8-1.fc20 has been submitted as an update for Fedora 20.
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.
Package anaconda-20.25.14-1.fc20, python-blivet-0.23.8-1.fc20:
* should fix your issue,
* was pushed to the Fedora 20 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing anaconda-20.25.14-1.fc20 python-blivet-0.23.8-1.fc20'
as soon as you are able to.

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.
anaconda-20.25.14-1.fc20, python-blivet-0.23.8-1.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report.
