Fedora 23 image is corrupted (examples/Dockerfile.simple)

[MarSik]

I get an error when trying the example like this:

vocker --debug build --tag simple -f ~/vocker/examples/Dockerfile.simple

or this

/usr/bin/virt-builder --format=qcow2 --no-check-signatures -o /root/.cache/vocker/images/fedora-23.qcow2 fedora-23

The error in both cases is:

virt-builder: mount: /dev/sda3 on / (options: ''): mount: wrong fs type, bad option, bad superblock on /dev/sda3,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so. (ignored)
virt-builder: mount: mount: /boot: No such file or directory (ignored)
virt-builder: error: libguestfs error: is_dir: is_dir_stub: you must call 
'mount' first to mount the root filesystem

If reporting bugs, run virt-builder with debugging enabled and include the 
complete output:

  virt-builder -v -x [...]

• My SELinux is in Permissive mode
• I have a+x set for the /root hierarchy
• Trying the same with Fedora 22 works fine.

I can not reproduce this issue:

# virt-builder --format=qcow2 --no-check-signatures -o /root/.cache/vocker/images/fedora-23.qcow2 fedora-23

@MarSik , can you please remove the image from the virt-builder cache in ~/.cache/virt-builder and try again?

[MarSik]

Here is the log file. I can download the image fine when using virt-builder. But vocker fails with the reported error. Even after clearing all caches in ~/.cache/vocker and virt-builder.

I tested the same example file with f22 and f24. Fedora 22 image works fine, Fedora 24 fails (but not so spectacularly).
