### Common Issues <a href="#common-issues" id="common-issues"></a>

**Permission Problems**

If you encounter permission issues:

```
# Set proper directory permissions
sudo chmod -R 755 /var/lib/soika
sudo chown -R $(whoami):$(whoami) /var/lib/soika
```

**NVIDIA drivers issue**

```
If the issue like below:

root@soika-admin-SYS:/var/lib/soika/soikastack_logs# nvidia-smi
Failed to initialize NVML: Driver/library version mismatch
NVML library version: 550.144

Fix by running this command and then run the nvidia-smi command again

sudo apt update && sudo apt full-upgrade
```

**Network Connection Issues**

If you experience network connectivity problems during installation:

1. **Check DNS resolution:**

   ```
   ping 8.8.8.8
   nslookup s3.dualstack.eu-central-1.amazonaws.com
   ```
2. **Check proxy settings if applicable:**

   ```
   echo $http_proxy
   echo $https_proxy
   ```
3. **Test connectivity to download servers:**

   ```
   curl -I https://s3.dualstack.eu-central-1.amazonaws.com
   curl -I http://47.128.72.20
   ```
