Error message

Description of problem:

After running preupgrade in F16 and rebooting, anaconda starts, prompts for the LUKS password, and then error "Unable to read package metadata. This may be due missing repodata directory..." occurs.

How reproducible:


Steps to Reproduce:
1. in F16 run `yum update; yum install preupgrade`
2. run preupgrade
3. reboot to preupgrade
Actual results:

Error is shown

Expected results:

Upgrade is completed sucessfully

Comment 1 Josef Skladanka 2012-05-15 13:25:59 UTC
Setting as F17 blocker

Comment 2 Brian Lane 2012-05-15 15:06:45 UTC
When Anaconda fails Please switch to tty2 (ctrl-alt-f2) and attach
the logs from /tmp/*log to this bug as individual plain/text files.

Comment 3 Adam Williamson 2012-05-15 16:26:56 UTC
it rather sounds like the reproduction scenario should also include 'have a LUKS-encrypted partition on the system to be updated'...

Comment 4 Adam Williamson 2012-05-15 18:09:53 UTC
At a first try, I can't reproduce this with current F16 preupgrade and dl.fedoraproject.org as the server, no LUKS partition on the system to be upgraded. I'll try again with a LUKS partition.

Comment 5 Adam Williamson 2012-05-16 06:02:23 UTC
Can't reproduce with a LUKS partition on the system to be upgraded, either. Neither can tflink. What partitions were encrypted, exactly? Is it possible you entered the passphrase incorrectly?

Comment 6 Josef Skladanka 2012-05-16 09:27:07 UTC
Sadly, I upgraded by other means since, and an unable to reproduce the issue. So I guess the only thing here is to close it as notabug?

Comment 7 Adam Williamson 2012-05-16 16:59:54 UTC
If two others can't reproduce and neither can you and you don't have the logs, then yeah, we'll have to close it. :/

Comment 8 Bill C. Riemers 2012-06-06 21:32:05 UTC
Same problem.  I have full disk encryption, which means everything except /boot, and the windows junk that was shipped on the laptop.  I tried repeating the procedure several times, and each time I get the same error.   Incidently a second bug is when it prompts for the password it only accepts QWERTY input, even though my keyboard layout is normally DVORAK.  I had to key in my passcode about twenty times to get it right... :(

I'm going to try it again right now, so I can collect the logfiles.   In the mean time here is some other information that may be useful:

Comment 9 Bill C. Riemers 2012-06-06 21:33:24 UTC
Oh I don't know if it is relevant, but I also have my router setup as an autoproxy.  I guess that might effect things if pre-upgrade tries to collect data from the internet when booted from the upgrade image.

log files

Here are the log files.  I think though in the process of capturing them I spotted the bug:

[root@briemersw /]# lvscan
  ACTIVE            '/dev/vg_docbillthink/lv_root' [25.53 GiB] inherit
  ACTIVE            '/dev/vg_docbillthink/home' [105.00 GiB] inherit
  ACTIVE            '/dev/vg_docbillthink/swap' [8.00 GiB] inherit
  ACTIVE            '/dev/vg_docbillthink/root' [51.06 GiB] inherit
  ACTIVE            '/dev/vg_docbillthink/data' [144.97 GiB] inherit

Here is the problem both lv_root and root are root partitions.  lv_root is from Fedora 14, root is my current root partition.  When I copied the log files to /mnt/sysimage/. and then rebooted them, the files where not in / upon reboot.  So the problem is simply pre-upgrade is using the wrong root!!!   Apparently, it is not setting an option to pass that information to itself on reboot, so it is just grabbing the first partition it think's looks like a root partition.

I will write a leading block of 0's to lv_root to temporarily disable it, and see if preupgrade then picks up the correct root partition.


Comment 11 Bill C. Riemers 2012-06-07 00:10:42 UTC
Indeed that was the problem.  It looks like this bug is actually caused by something completely different than in the subject.  Would you like me to change the bug to reflect the actual problem, or clone this bug to create a new one with the appropriate subject?

The fix would be to either create a unique file in the root filesystem than preupgrade could find later when scanning for root, or to pass an argument with grub to let preupgrade know what the root file system uuid is, or that information could just be written to the boot image.

Comment 12 Adam Williamson 2012-06-07 18:47:41 UTC
Please create a new bug.

Comment 13 Brad Hubbard 2012-07-02 05:10:10 UTC
I experienced this myself and this is what I found (for the benefit of those who end up here).

Aa a precaution I always create an LV called "rootcopy" and copy the root LV to it before upgrading. I did this and then ran "preupgrade" and rebooted and was met with the issue mentioned in the OP. I then looked at what was mounted and found that my "rootcopy" LV had been mounted as / instead of my actual root LV. I modified /boot/preupgrade/ks.cfg from this...

# ks.cfg generated by preupgrade
lang en_US.UTF-8
keyboard us
bootloader  --upgrade --location=none
clearpart --none
upgrade --root-device=UUID=None

grubby --remove-kernel=/boot/upgrade/vmlinuz
rm -rf /boot/upgrade /var/cache/yum/preupgrade*

to this...

# ks.cfg generated by preupgrade
lang en_US.UTF-8
keyboard us
bootloader  --upgrade --location=none
clearpart --none
upgrade --root-device=UUID=da9d723f-4de1-4267-b189-4ad1d9c72606

grubby --remove-kernel=/boot/upgrade/vmlinuz
rm -rf /boot/upgrade /var/cache/yum/preupgrade*

... and all was good (that UUID is of course the UUID of my actual root (/) partition (in my case an LV).

So that explains what happened and how to fix it but not why.
