<summary>1.Multipass connection error</summary>

### Problem Description&#x20;

When encountering the error message: "`cannot connect to the multipass socket`", it's usually related to driver configuration.

### Troubleshooting Steps&#x20;

1. First, check current driver settings:&#x20;

```
multipass get local.driver
```

2. Check the output:

* If you're using VirtualBox as virtualization platform, output should show `virtualbox`
* If output shows `hyperv` , you'll need to change the driver settings

3. To switch to VirtualBox driver, execute this command:&#x20;

```
multipass set local.driver=virtualbox
```

4. Follow-up Actions:

* If issues persist after above steps, run the repair function in Multipass installer
* Restart related services after repair

### Important Notes

* Ensure VirtualBox is properly installed on your system
* Administrative privileges required for executing commands
* Multipass services may need restart after driver modification
