bug#39685: Error on guix-pull using the qemu image

[Gábor Boskovits]

Hello,

Eilene Tomkins-Flanagan via Bug reports for GNU Guix <address@hidden> ezt írta (időpont: 2020. febr. 20., Csü 5:31):

I downloaded the qemu image from https://ftp.gnu.org/gnu/guix/guix-system-vm-image-1.0.1.x86_64-linux.xz. It had a valid signature.

After booting the machine with qemu 3.1 (I'm on debian-amber):

`qemu-system-x86_64    -net user -net nic,model=virtio    -enable-kvm -m 512    -device virtio-blk,drive=myhd    -drive if=none,file=./guix-system-vm-image-1.0.1.x86_64-linux,id=myhd`

-m 512 looks a bit low.

I tried installing hello for the guest user. It worked fine.

I then tried running `guix pull && guix package -u`, and received the following error:

```

[...]

Backtrace:

          0 (apply-smob/1 #<catch-closure 6a2bbc0>)

 

ERROR: In procedure apply-smob/1

```

On the second attempt, it failed immediately with this message:

```

Please report it by email to <bug-guix.gnu.org>

```

After asking on the IRC to find out if I'd made a mistake, they directed me to send in the error as the message said.

Could you check if the disk is full? The image is small should be resized before use.

Let me know if other info is necessary for reproduction.
