[Error] Distrobox fails to create nvidia container

**Describe the bug**

When trying to build distrobox, it fails with error

```

```

It seems to be trying to eval the banner of Nvidia containers.

**To Reproduce**

distrobox.ini
```
[cuda-dev]
image=docker.io/pytorch/pytorch:2.8.0-cuda12.6-cudnn9-devel
nvidia=true
init=true
additional_packages="systemd dbus dbus-user-session iproute2 procps"
```

command
```
distrobox-assemble create --file ./distrobox.ini
```

**Expected behavior**
Distrobox created without error
