[Error] assemble does almost everything, except the exports

Please, before opening a bug:

- make sure you've read the documentation.
- Ensure there isn't already an open issue about this.
- Ensure there isn't already a closed/resolved issue about this.

**Describe the bug**
Assemble creating an Ubuntu container does almost everything but fails to export the apps with the message: `touch: setting times of '/dev/null': Permission denied`. Only Ubuntu images (devel, rolling) fails like this.

**To Reproduce**
`distrobox assemble create --file ubuntu.ini`

```ini
[zz-bx_ubuntu]
# --- UBUNTU ---

# next version (bleeding edge)
#image=docker.io/ubuntu:devel
# current version
image=docker.io/ubuntu:rolling
# current LTS version
#image=quay.io/toolbx/ubuntu-toolbox
#image=docker.io/ubuntu:latest

pull=false
#init=true
init=false
entry=true
start_now=true
replace=true
root=false

unshare_ipc=false
unshare_netns=false
unshare_process=false
unshare_devsys=false

nvidia=false

home="/stor/sys/_ct_/data_box/ubuntu/home"
volume="/stor:/stor"

#additional_packages="sudo libnss-myhostname"
additional_packages="mono-complete"
additional_packages="keepass2"
additional_packages="dupeguru"
additional_packages="qdirstat"
additional_packages="freefilesync"

exported_apps="keepass2"
exported_apps="dupeguru"
exported_apps="qdirstat"
exported_apps="FreeFileSync"

#exported_bins=""
#exported_bins_path=""
```

**Expected behavior**
Container successfully created with exports to the host desktop shortcuts.

**Logs**
Run the commands with `--verbose` and post the log here as a file upload
Attach also the output of `podman logs` or `docker logs`, possibly with `--latest` flag

[container.log](https://github.com/user-attachments/files/24629783/container.log)

**Desktop (please complete the following information):**

- Are you using podman, docker or lilipod?_podman_
- Which version or podman, docker or lilipod? _5.7.1_
- Which version of distrobox? _1.8.2.2_
- Which host distribution? _Arch Linux_
- How did you install distrobox? _pacman_

**Additional context**

I've run the same export parameters using Debian container and it works fine.
