```
Installer downloads prefer IPv4 by default because some networks have broken or
slow IPv6 paths to `ollama.com`. Override with
`LAB_OLLAMA_INSTALL_CURL_IP_VERSION=` if you want curl's automatic behavior.
If the Debian host cannot reach `ollama.com`, download the matching Linux
tarball from another machine, copy it to Debian, and point `jeannie` at it:
```bash
curl -L https://ollama.com/download/ollama-linux-amd64.tgz -o /tmp/ollama-linux-amd64.tgz
scp /tmp/ollama-linux-amd64.tgz jv@192.168.100.73:/tmp/
LAB_OLLAMA_TARBALL_FILE=/tmp/ollama-linux-amd64.tgz ./jeannie ollama-setup
```
The same fallback is available to the Ansible bootstrap with
`debian_pc_ollama_tarball_file`.
