Hermes SEG End of Support for Ubuntu Server 18.04 LTS and Upgrade Path

Hermes SEG version 18.04 is based on Ubuntu Server 18.04 LTS (Bionic Beaver). On May 31, 2023, Ubuntu will reach the end of the standard five-year maintenance window for Long Term Support (LTS) for 18.04 which means there will be no more bug fixes or security patches unless you opt to upgrade to Ubuntu Pro which will extend support to 2028 or upgrade your Ubuntu installation to a higher version. Consequently, Hermes SEG is no longer supported on Ubuntu 18.04 LTS.

Fortunately, if you have an existing Hermes SEG installation on Ubuntu 18.04 LTS, you can perform a release upgrade to Ubuntu Server 20.04 LTS (Focal Fossa) which will extend the standard maintenance window to May 31, 2028.

We have posted a detailed guide on how to successfully perform a release upgrade from Ubuntu Server 18.04 LTS to Ubuntu Server 20.04 LTS. Please follow the link below to access the guide on our Docs site:

If you run into any issues with the upgrade, you can post your question on our GitHub Issues page or our Matrix Community Chat channel.
