Known Issues
Here are some known issues that should be resolved in later releases:
- You cannot do an in-place upgrade from 2.3 to 2.4. We are still investigating data migration.
- Security Onion Desktop is still considered experimental. It should work when installing from our ISO image but will not work for network installations currently.
- File extraction may not work if you've manually switched from the default of Zeek metadata to Suricata metadata.
In-place Upgrades
If you have an existing installation of 2.4 RC1 (not Beta), then you should be able to update to RC2 via soup. Please be aware of a couple of issues:
- Due to a bug in RC1, you may be prompted to re-run soup up to four times so that it gets fully updated.
- Soup may fail due to a non-critical error while updating Elastic Fleet (more likely with Import or Eval installations).
- If you upgrade an Import or Eval installation and do not have new logs coming in, then you may need to go to Elastic Fleet - Settings - Outputs - so-manager_elasticsearch - Actions and enable both options at the bottom marked "Make this output the default".
- Elastic Agents are not automatically updated.
- If you tried to run soup before this announcement was posted, then you may need to run the following command to remove any old remnants:
sudo rm -f /tmp/supersoup/soup*
For more information about soup, please see:
https://docs.securityonion.net/en/2.4/soup.html
Transition from 2.3 to 2.4
When we release the final version of Security Onion 2.4, we will announce an End Of Life (EOL) date for Security Onion 2.3. Security Onion 2.3 will continue to receive security patches and priority bug fixes until it reaches EOL.
