Problem
Fresh Ubuntu install (Lenovo IdeaPad 3-15ADA05, kernel 6.17.0-20-generic, Node 22.22.2). OpenClaw 2026.4.15 installs & onboarding completes, but agent is completely silent. Messages accepted, yet no response appears in dashboard (127.0.0.1:18789) or Telegram (@Lutiekbot).
This exact issue repeats every time after clean reinstalls (npm uninstall -g openclaw + rm -rf ~/.openclaw + reboot + fresh install). Started right after today's Ubuntu reinstall.
Key status --deep summary
Gateway: running, reachable, RPC probe OK, systemd active
Telegram: ON + OK (token valid)
OpenRouter: auth OK, probe succeeds (~18s)
Session: openrouter/auto or /free
Memory: enabled (memory-core) but unavailable
Tried repeatedly
Skipped most onboarding options (skills, plugins, hooks)
openclaw gateway restart, systemctl restart, model pinning (/model openrouter/free etc.)
/new, /reset, new sessions, hard refresh
openclaw logs --follow (no clear errors)
openclaw doctor (archived orphan file)
Multiple full clean uninstall/reinstall cycles
Gateway, auth & channels look healthy β agent never replies.
Reproducibility
100% on this machine post-Ubuntu reinstall. Did not occur on previous setup.
Extra info available
Full logs after test message

Looks like system-level issue on Ubuntu 6.17 (AppArmor? systemd user session? kernel/loopback? missing libs?) that survives clean reinstalls.
Happy to run any debug commands.
