Description Steve Tyler 2010-02-27 22:08:52 UTC 
Created attachment 396796 [details]
screenshot showing "an unhandled exception has occurred" and python backtrace

Description of problem:
Just after attempting to save a custom disk layout, the installer popped up a dialog announcing that "an unhandled exception has occurred". At the end of the reporting process, I clicked "Exit installer", after which the display was black except for a functional pointer. The consoles worked, and I had to reboot from a console.

Version-Release number of selected component (if applicable):
http://serverbeach1.fedoraproject.org/pub/alt/stage/13-Alpha.RC4/Fedora/x86_64/iso/Fedora-13-Alpha-x86_64-netinst.iso

How reproducible:
Twice now:
1. live ISO on a USB stick (Bug 568556).
2. netinst.iso on a CDRW.

Steps to Reproduce:
Bug 568556
The second time, I actually was configuring two partitions and a logical volume.
  
Actual results:
Bug 568556

Expected results:
Bug 568556

Additional info:
Bug 568814 - live install exceptions include /tmp/syslog, but /var/log/dmesg should be used instead
Bug 569057 - DiskLabelCommitError: Could not commit to disk /dev/sdb5

screenshot showing save to local disk dialog

Wouldn't the local disk be ram disk? (I didn't investigate this path further ... chose the Bugzilla option)
The installer corrupted the disk partition I would have preferred to save to -- it couldn't be mounted from a console. I found another partition to mount and save the screenshots to. The installer environment does not appear to create logical volume devices (/dev/mapper is empty except for "control"). If my entire disk were configured as a volume group, there would not be anywhere to save. Maybe a USB stick?

Same message when booted into F12:
[root@walnut mnt]# mkdir foo
[root@walnut mnt]# mount /dev/sdb5 foo
mount: you must specify the filesystem type
[root@walnut mnt]# mount -t ext4 /dev/sdb5 foo
mount: wrong fs type, bad option, bad superblock on /dev/sdb5,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

My password is 16 random alphanumeric characters -- I do not have it memorized. I have put in a text file. That text file is on a logical volume, which could not be mounted. Fortunately, I have a copy on my laptop so I typed it in instead of using copy/paste. There is no way to make the password visible in this dialog.

[Skipped over a few screenshots ...]

Am I supposed write that number down? (rhetorical)
Clicked "Exit installer".

Why do I need to click "Exit installer" again?

Of course I did ... and immediately got a black screen.

Also, it says the "error file" was "written", even though I uploaded it to Bugzilla.
Comment 5 Hans de Goede 2010-03-01 10:21:32 UTC 
Steve,

May I summarize this bug with "System does not reboot after clicking exit installer after an exception" ?

Ales,

I think this is a reboot issue (see above), since you last worked on the reboot
code I'm assigning this to you.

Regards,

Hans
Comment 6 Ales Kozumplik 2010-03-09 10:59:39 UTC 
This is actually two different problems:

1) having to press 'exit installer' twice, for that see 571727.
2) anaconda does not reboot when it should. I will track progress on that one in this bug.

> This is actually two different problems:

OK. I turned this bug into a commentary on the exception handling feature generally, and it seemed like it be would easier to step through the screenshots all in one bug.

> 1) having to press 'exit installer' twice, for that see 571727.

Thanks. I am CCed on Bug 571727 (FYI, BZ will auto-generate bug links with the syntax "Bug NNNNNN").

Thanks.
Comment 8 Ales Kozumplik 2010-03-09 12:45:39 UTC 
I verified that the black screen and text "press cad to reboot" on tty1 is behavior identical to F12, so this is not a regression. Question is whether this should be remedied and how. Will talk to python-meh experts.

Yeah, thanks. I always forget.

For the F13, we'll have to wait to see if the next blocker meeting retains this bug as a F13Blocker and either push or close this as fixed rawhide.
