Arch Linux

python-paramiko is listed in the [list of dependencies](https://github.com/Xpra-org/xpra/blob/master/docs/Build/Dependencies.md)

without paramiko, the server will throw a non-fatal error:

```
2023-08-27 07:12:11,325 Error: cannot enable SSH socket upgrades:
2023-08-27 07:12:11,325 No module named 'paramiko'
```

it's mainly used for speed optimizations

python-pyxdg unfortunately is more obscure, it's not listed in the generic [list of dependencies](https://github.com/Xpra-org/xpra/blob/master/docs/Build/Dependencies.md), but it is listed in the [list of debian dependencies](https://github.com/Xpra-org/xpra/blob/master/docs/Build/Dependencies.md)

without the xdg module, the server will throw a warning and a non-fatal error:

```

it is used to parse the list of desktop entries on the server side and make it available to the client
