Just adding some additional context - possible bug or compatibility issue with 24.04.

Ran into this problem with latest version of MAAS 3.4, and attempting to commission nodes with 24.04. Downgraded commissioning to 22.04 and it succeeded.

Temporary workaround I used:

Create a custom commissioning script "10-maas-extra-packages" with the contents:

```
#!/bin/bash

apt update
apt -y install isc-dhcp-client
```

This gets executed prior to 20-maas-02-dhcp-unconfigured-ifaces, which then runs successfully.
