Troubleshooting

pyro env pull or first-run install fails

Cause:

  • the environment cache directory is not writable
  • the configured registry artifact is unavailable
  • the environment download was interrupted
  • the host cannot reach registry-1.docker.io

Fix:

pyro env inspect debian:12
pyro env prune
pyro env pull debian:12

If you are validating a freshly published official environment, also verify that the corresponding Docker Hub repository is public.

pyro run fails closed before the command executes

Cause:

  • the bundled runtime cannot boot a guest
  • guest boot works but guest exec is unavailable
  • you are using a mock or shim runtime path that only supports host compatibility mode

Fix:

pyro doctor

If you intentionally want host execution for a one-off compatibility run, rerun with:

pyro run --allow-host-compat debian:12 -- git --version

pyro run --network fails before the guest starts

Cause:

  • the host cannot create TAP devices or NAT rules

Fix:

pyro doctor

Then verify:

  • ip
  • nft or iptables
  • /dev/net/tun
  • host privilege for sudo -n

pyro doctor reports runtime issues

Cause:

  • the embedded Firecracker runtime files are missing or corrupted

Fix:

  • reinstall the package
  • verify pyro doctor reports runtime_ok: true
  • if you are working from a source checkout, ensure large runtime artifacts are present with git lfs pull

Ollama demo exits with tool-call failures

Cause:

  • the model produced an invalid tool call or your Ollama model is not reliable enough for tool use

Fix:

pyro demo ollama -v

Inspect:

  • model output
  • requested tool calls
  • tool results
