Update Manager

Scans VM/CT in Proxmox VE to identify available updates including security patches. Read-only — provides visibility into pending updates without making changes.

Features

  • Security Patches

    Identify critical security patches across VMs and containers.

  • Update Inventory

    View available updates by system, package, and severity level.

  • On-demand or scheduled

    Trigger a run manually from the UI, or schedule recurring runs with a cron expression — the Settings panel includes a quick link to crontab.guru to validate your expression.

  • Read-Only Scanning

    Check for updates without making system changes.

  • Export PDF / Excel

    Download results as PDF (colored table with footer and page numbers) or Excel (autofilter-enabled sheet for slicing, pivoting and sharing). Format chosen from a split-button dropdown.

  • Parallel Scanning

    Configurable MaxParallelRequests (default 5) speeds up scans on large clusters; set to 1 to fall back to sequential mode. A failure on one resource is isolated to that item — the rest of the scan keeps running.

  • Notifier Integration

    Attach the generated report to a notification using any of the configured Notifier channels — handy for nightly cron-based runs.

Why

Why centralise update checks when apt list --upgradable already exists?

One view, every VM

See pending updates across all running VMs and CTs of the cluster on a single page — no per-host SSH session, no script-on-script.

Security signal isolated

Each row carries Normal / Security / Reboot-required flags so the security backlog never gets buried in the rest.

Read-only by design

The module never patches anything. Safe to schedule and forget — you stay in control of when and how to apply updates.

One broken VM doesn't break the run

SSH timeout, missing agent or parse error are isolated to that single item — the rest of the scan completes and the failure surfaces in the report.

Sections

  • Scans — live grid of every running VM/CT with its current scan status (Ok / InError / Cancelled), available updates (Normal / Security), reboot required flag. Trigger a new scan, download the report as PDF or Excel
