EVE-NG (Emulated Virtual Environment – Next Generation) relies heavily on specific QEMU wrappers, Linux kernel configurations, and base Ubuntu packages. When updates introduce major changes—such as the recent migrations from Ubuntu 20.04 to Ubuntu 22.04 or the transition to multi-user changes—older, unoptimized node templates can stop functioning entirely.

Let's assume you have found an old ISO (e.g., EVE-ng-Community-v3.2.1-12.iso ). You are currently on v5.x and want to roll back.
Some network instructors and training centers prefer to keep a consistent environment across all students. Upgrading to a version with a different UI, changed menu layouts, or new icon sets can create confusion. Staying on a proven version ensures a uniform learning experience. : Run apt update to refresh package lists
The Community Edition v5 introduced a backup manager that can export and restore labs and database settings.
even if prompted by the command-line interface (CLI). EVE-NG relies on specific libraries. As of early 2026, EVE-NG Community Edition typically operates best on specific Ubuntu versions, and upgrading the OS will break the EVE-NG functionality. 3.2 Step-by-Step Update Process (CLI) Let's assume you have found an old ISO (e
EVE-NG does not maintain a public archive of every previous release on their main download page. If you are looking for a specific older image, you generally have three avenues:

EVE-NG is the successor to UNetLab, built to allow network engineers to emulate real network devices using actual vendor images — from Cisco, Juniper, Huawei, Nokia, Palo Alto, and many others. It runs as a virtual machine (via OVA/OVF packages) or can be installed directly on bare metal using an ISO image.
New software updates occasionally introduce bugs or break compatibility with existing setups. Below are the primary reasons you might need to roll back or install a legacy version of EVE-NG.
