Review comment (suggestion):
This can be combined with the curl to avoid writing to a file

```
curl -fsSL "https://ollama.com/download/rocm-amd64-deps.tgz${VER_PARAM}" \
    | $SUDO tar zx --owner ollama --group ollama -C /usr/share/ollama/lib/rocm .
```

`--owner` and `--group` seems to be implementation specific. Debian-based distros seems to have this flag but I would check some others to be sure
