Keep diagnosis, package repair and security triage as separate decisions, with a recovery plan for any approved change to the firewall. ## Source fact: what the authority says The [OPNsense firmware guide](https://docs.opnsense.org/manual/firmware.html) describes the Packages tab as a place to inspect licenses, force reinstalls and lock versions. Its cleanup audit immediately removes temporary update files, while the connectivity audit points to possible update connectivity problems. The health audit can uncover installation and disk or filesystem problems; the upgrade audit exposes the package upgrade log after a major upgrade. The security audit compares installed package versions with a database of known vulnerabilities for triage and inspection. ## What the source does not establish The documented audits are troubleshooting and inspection tools, not proof that a particular installation was exploited. An example repair or likely update outcome is not a guarantee that it applies to the observed firewall fault. ## Applicability questions - What exact error, release and package-manager state were observed? - Is the immediate question connectivity, filesystem health, upgrade history or a known-vulnerability match? - Which prior troubleshooting actions have already changed the evidence? - Who can approve the repair and restore management access if it fails? ## DSE recommendation: controlled next steps The following steps are DSE recommendations based on the cited source. DSE recommends keeping the original error text and time beside the selected audit. Start with the question the audit can answer. Avoid running cleanup as a harmless collection step: classify it as an action in the maintenance record and preserve the evidence required before it is used. For a connectivity fault, ask the firewall owner to review the relevant DNS, address-family and external-address configuration through the approved procedure. Do not copy a diagnostic suggestion that disables a rule into a live incident without reviewing its impact and a reversal step. For a suspected package-manager fault, match the exact message to the current official instructions before proposing a reinstall. Name the package and expected post-repair observation. Keep a broader operating-system recovery decision outside a narrowly approved package repair. Route vulnerability matches to the security owner with the installed version and source finding. Ask for a documented disposition and update plan. Preserve unresolved findings instead of declaring the installation clean merely because an unrelated health or connectivity audit completes. ## Verification and evidence Proposed verification: on an approved representative system or maintenance path, retain the chosen audit output and compare it with the original problem. If a repair is authorized, rerun the specific failed operation and record the resulting package-manager state, updater response and management reachability. Keep the pre-repair evidence, exact action and post-repair observation on one timeline. Review any continuing error before repeating the same intervention. Accept a repaired updater, a completed upgrade and the disposition of a security finding separately; none should be inferred from the label of another audit. ## Official references - [OPNsense — Firmware](https://docs.opnsense.org/manual/firmware.html) — official product documentation; confirm the installed release and configuration.
