Subject: Null pointer error when partitioning with the graphical installer
Date: Wed, 22 May 2019 20:53:05 +0200

Hello,

Thank you for all the work you've put in the Guixsd release.  I have
used guix on top of a Debian distribution for some time, but with the
release I wanted to try and install it on its own.

I'm trying to install guix on my system.  I have the 1.0.1 patch, but I
had the same problem with 1.0.0.

I already have a debian system with an encrypted drive, and I would like
to erase it with an encrypted Guix system with a separate /home partition.

I have chosen my language (français).

My location (France).

I have chosen the graphical installer.

I have chosen my timezone (Europe / Paris).

I have chosen my keyboard (Français / Français (sans touche morte Sun):
this one seems to be correct but I don't have much information.  It
would be awesome if I could test it in a text box).

I have chosen the guided installation with encryption.

I have chosen my hard drive, the only option:
ATA WDC WD15EARS-60M (scsi) /dev/sda 1500 GB gpt

I have chosen the option to have a separate /home.

And then I get the exception.  I copy it from another keyboard, but I
hope that I copied it correctly.

We fixed a bug similar to what you describe in 1.0.1:

  https://issues.guix.gnu.org/issue/35783

Can you confirm that the backtrace you posted comes from 1.0.1 and not
1.0.0?  (It seems to be from 1.0.1 accordingly to the line numbers, but
better be on the safe side.)

Is it 100% reproducible for you?

Could you post the output of “fdisk -l /dev/sda” (hit Ctrl-Alt-F3 and
run that command)?

Does the problem occur when you choose the “manual partitioning” method
instead of “guided partitioning”?

Thanks,
Ludo’.

Hello,

Thank you for your answer.

> 1.0.0?  (It seems to be from 1.0.1 accordingly to the line numbers,
but

After backing up my data, I re-downloaded the guix image from the
website, burnt it, and booted it.  The boot screen reads
"1.0.1-1.8204295".

I also had an error during the loading with an error in finalization
thread: Bad file descriptor (twice, reproducible) but no additional
info, right after ssh-keygen.  Is there a log file for that?  I had
very
little time to catch it.

> Is it 100% reproducible for you?

Except for the bytestructures (but with the same loop at 863:17), I
reproduced it 4/4 times with a full reboot, and 4/4 times without a
full
reboot.

> Does the problem occur when you choose the “manual partitioning”

So I use the same language and such and select the manual partitioning:
I get to a screen with the 3 partitions already present on my 1.5T
disk:
 - 1 537MB fat32 boot,esp /boot/efi
 - 2 256MB ext2
 - 3 1500GB

If I select the second partition, I get another reproducible (2/2 with
full reboot) backtrace:

ice-9/eval.scm:159:9: Unhandled ext2 fs-type

I've managed to avoid the problem with a manual partitioning
procedure, selecting my hard drive, selecting "gpt" to get rid of the
existing ext2 partition.

Then I go to create a single root partition (with the idea of
re-installing guix with the default cryptsetup options once the ext2
partition is forgotten), but then I get another "null pointer
dereference" exception -- this one is longer :(

I reboot and the partition table is erased (good thing I updated my
backups just before the operation ;) less so that I don't have an
operating system on my main computer and have to use this one :(

However, selecting the automatic method for whole disk encryption
still gives the first error, and trying to add a partition manually
gives the second.

I wanted to give it before the GPT erasure but I thought I could save
it
to / on the Guix installer, and it did not work.  So I only have the
log
after the procedure:

And here is the error that came with it in red:

GPT PMBR size mismatch (2694403 != 7831551) will be corrected by write.
The backup GPT table is corrupt, but the primary appears OK, so that
will be used.
The backup GPT table is not on the end of the device. This problem will
be corrected by write.

I remember that a similar error happened when I had the previous GPT
table, but I don't remember the exact wording.  So maybe there is
still a backup of the GPT table that still has the ext2 partition?

Anyways, I have saved all my data and have a rainy-days computer at
hand, so the situation is not so bad.

Hello Vivien,

Thank you very much for the detailed report and sorry about all those
errors :(

So this one is easy, it's yet another unsupported fs type. Maybe the fix
would be to get rid of libparted fs types -> <user-partition> fs types
conversions like discussed with Danny.

Otherwise, we'll have to maintain conversions for every kind of
partitions in user-fs-type-name, user-fs-type->mount-type and
partition-filesystem-user-type procedures.

These are annoying but harmless.

That’s terrible.  :-/  That’s on x86_64, right?

(In the meantime you could the “manual” installation method:
<https://www.gnu.org/software/guix/manual/fr/html_node/Installation-manuelle.html>.)

As Mathieu notes, there’s one bug for which the fix is clear, but the
null-pointer exception is pretty bad, especially if we cannot reproduce
it easily.

Let’s see what can be done…

Thank you for testing thoroughly and for providing a detailed bug report!

Ludo’.

Hello,

I have issued 

dd if=/dev/zero of=/dev/sda 

for a couple of minutes, then create a new gpt partition table with
cfdisk (and write it) in the hope that I would be able to proceed with
the guided installer with a fresh partition table, but I still get the
null pointer dereference.  So i guess the ext2 partition is not
responsible for this one.

Yes, it's a x86_64 (intel i3).

Hello,

I have installed with the manual method, it worked, I rebooted but my
luck ends here: after entering my decryption key twice (the first time
with a keyboard configured as US, the second with my azerty
configuration, is this normal?  Whatever I can add a new luks key with
the US keyboard), I get a boot screen reading:

GC Warning: pthread_getattr_np or pthread_attr_getstack failed for main
thread
GC Warning: Couldn't read /proc/stat

The success error and pcspkr are also printed when running the
installer.

I have 2 partitions: /dev/sda1 is the 512MB ESP partition, and
/dev/sda2 is the fully encrypted disk (named 'guix-root').  Except for
the keyboard configuration, UUIDs and default user, I have kept the
default 'desktop' configuration.scm.

There is no disk activity, no fan activity and it does not respond to
C-M-Fn, but it does reboot on C-M-DEL.

And if I re-run the graphical installer, I still get the null pointer
dereference.


So I will revert to having guix on top of another distro for now.



Best regards,

Vivien

Keyboard layouts are managed separately for grub, the console and X.

Have you tried to press 'Enter'?

Also, could you email your configuration file?
