Set NOT_SECURED=true in postiz install script for local/non-secured setups. In simplelogin install, detect the venv site-packages path and create a minimal newrelic package stub (newrelic/__init__.py and newrelic/agent.py) with no-op record_custom_event and initialize functions to avoid import errors when New Relic is not present.
- New preflight_repo_access() warns if enterprise repos are active without subscription
- Scans /etc/apt/sources.list.d/ for enterprise.proxmox.com entries
- Tests HTTP access (detects 401/403 Unauthorized)
- Warning only — not a blocker (packages come from pve-no-subscription repo)
- Move run_preflight from build_container() into install_script() after header_info
- Shows: Header → preflight checks → 2s pause → clear (via next header_info call)
- On failure: show summary + exit cleanly (no ERR trap)
- Change all return 1 → return 0 in preflight functions (prevents ERR trap under set -Ee)
- Remove PREFLIGHT_DONE guard from build_container (no longer needed)
Introduce preflight_template_available() in misc/build.func to verify a matching OS/version template exists locally or in the online pveam catalog, and to fail early with a helpful list of available versions when none is found (exit code 225). Integrate this check into run_preflight. Also move the run_preflight invocation inside install_script to run after header_info (so preflight output is visible) and remove the earlier preflight call.
Add preflight/validation exit codes and telemetry reporting for aborted preflight checks. Introduces new exit codes (103-110) and maps them to a new "preflight" error category. Adds post_preflight_to_api(), a fire-and-forget telemetry sender that posts an "aborted" status and detailed error summary (only when diagnostics/UUIDs are present), and extends post_update_to_api() to handle an "aborted" status. Changes are defensive (no blocking failures, short curl timeout) and aim to improve analytics for validation/preflight failures.
