EVE-NG is a premier multivendor network emulation tool used by IT professionals for certification prep (CCNA, CCNP, CCIE) and enterprise network testing. It allows you to run real device images (Cisco, Juniper, Palo Alto) in a browser-based environment. Why Users Seek Old Versions

While the latest version (e.g., v5.0 or v6.5) is generally recommended, users sometimes look for older builds for specific reasons:

Feature Availability: Some older Community Edition versions (like 2.0.3-105) reportedly allowed certain multi-user functionalities that were later restricted to the Professional edition.

Hardware Compatibility: Older versions based on Ubuntu 16.04 may be the only option for legacy server hardware that cannot support the newer Ubuntu 20.04/22.04 base used in Version 5 and above.

Stability: Users with complex, working labs often avoid updates to prevent configuration breakages or "fix permissions" issues. Update and Download Risks

No Direct Upgrade Path: It is impossible to upgrade directly from the old Community Edition (Ubuntu 16.04) to the new Version 5 (Ubuntu 20.04). A fresh installation is required.

Security Concerns: Downloading .OVA or .ISO files from unofficial forums or personal drives carries high risk of malware. Always prioritize the Official EVE-NG Download Page.

Image Management: EVE-NG does not come with device images. You must manually upload your own qcow2 images via WinSCP or FileZilla to the /opt/unetlab/addons/qemu/ directory. EVE-NG Community Edition

Many users prefer the OVF method for older environments. You can import an OVF file

into VMware Workstation to quickly stand up a specific version without running a full OS installation. 2. Deep Guide: Updating an Existing "Old" Version

If you have an older version installed and wish to update it to a stable point (but not necessarily the absolute latest "bleeding edge"), follow these steps: Step 1: Preliminary Preparation Snapshot/Backup: Before any update, create a snapshot of your VM

or ESXi. This is critical as updates can sometimes break custom node configurations. Disk Space Check:

in the CLI to ensure you have enough space for temporary update files. Step 2: Update Package Lists Access your EVE-NG CLI via SSH (default: ) and run the following commands: apt update Use code with caution. Copied to clipboard

If you are trying to stay on an old version of the base Ubuntu OS (e.g., 16.04 or 18.04), avoid apt full-upgrade

as it may force a kernel change that EVE-NG does not yet support. Step 3: Execute the Upgrade

Run the upgrade command to pull the latest compatible binaries for your current version: apt upgrade Use code with caution. Copied to clipboard During this process:

When prompted about modified configuration files, it is usually safest to keep your current version

(choose 'N' or 'No') to avoid overwriting custom tweaks you've made to your lab environment.

If the system asks to upgrade the GRUB bootloader, generally select your main virtual disk to install it. Step 4: Post-Update Maintenance Clear Browser Cache:

This is the most common reason for the GUI not appearing updated or showing errors after a version change. Fix Permissions:

Essential for ensuring your node images (Cisco, Fortinet, etc.) still boot correctly: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. Copied to clipboard Finalize the process by typing 3. Troubleshooting "Old" Installations Repository Errors: apt update

fails, it may be because the Ubuntu repositories for your old version (like 16.04) have moved to "old-releases." You may need to edit /etc/apt/sources.list to point to ://ubuntu.com Windows Client Pack: Ensure your local PC has the latest EVE-NG Windows Client Pack

3. The .upd File Extension

Your search term included "upd." In the EVE-NG ecosystem, .upd usually refers to Update Packages rather than full installations.

If you are trying to download an old version and end up with a .upd file, you cannot use this to install the operating system from scratch. These files are meant to be applied on top of an existing EVE-NG installation via the CLI:

# Example command to apply an update
tar -xzvf eve-xxx.upd -C /
/opt/unetlab/wrappers/unl_wrapper -a update

If you are looking to install an older version from scratch, you need the ISO file, not the .upd file.

Part 6: The Smart Way – Managing Multiple EVE-NG Versions

Instead of constantly downloading old versions, use version-controlled VMs:

  1. Keep a “golden” old version (e.g., v2.0.3) as a linked clone in VMware.
  2. Export labs as .unl + images folder – they remain portable.
  3. Use Dockerized EVE-NG (experimental) – only for advanced users.

For team labs, consider running two separate EVE-NG instances:

  • old-lab.mydomain.com → version 2.0.3
  • new-lab.mydomain.com → latest version

This is the only foolproof way to avoid the “update destroyed my lab” nightmare.

Practical steps to acquire and deploy an older EVE-NG VM (recommended, assuming KVM/ESXi host)

  1. Locate ISO/OVA: search official downloads/archive or community GitHub releases.
  2. Verify checksum.
  3. Snapshot current environment.
  4. Deploy VM/OVA to test host (don’t replace production).
  5. Import required vendor images using the version-appropriate templates.
  6. Test labs and client connectivity (HTML5).
  7. Harden VM: firewall, limited user accounts, disable public access.
  8. Document differences and migration plan.

Phase 2: Wipe the Environment (Reinstall from Scratch)

Because EVE-NG uses a rolling database, downgrading in-place will break. The safest eveng old version download upd strategy is to:

  1. Delete the existing VM from your hypervisor (or create a new VM).
  2. Boot the old ISO you downloaded.
  3. Install EVE-NG as a fresh installation on a new virtual disk.
