System Update

Hermes SEG requires outbound TCP/80 and TCP/443 access to our update servers in order to check and download updates. 

Ensure you have a recent and valid backup of your system before installing updates.

Updates may contain breaking changes or additional steps that must be taken after the update gets installed, therefore ensure you check out the Release Notes for each update BEFORE installing. Updates are provided with absolutely no guarantees or warranties of any kind explicitly or implied and we are not liable for any damage that may occur to your system, service, cat, dog, car, house etc.. Simply stated, you are installing updates at your own risk. 

Hermes SEG updates are installed in order of release, in other words, System Update will not allow you to skip updates. If your system is behind more than one update, each update will have to be downloaded and installed individually. It's very important that you check out the Release Notes for each update.

System Update can be ran in the CLI as root. There is a Update script located at /opt/hermes/scripts/system_update.sh.

Each time you run the /opt/hermes/scripts/system_update.sh script, it will check for newer versions of itself as well as other required files. If new versions of the files are needed, it will download them automatically and exit. You must then restart /opt/hermes/scripts/system_update.sh in order to proceed with the update.

The script will initially ask you whether to to check for DEV updates. You should always answer NO to this prompt unless support has instructed you to check for DEV updates as part of troubleshooting. Installing DEV updates without support guidance will most likely break your system. Next, the script will ask you for the MariaDB/MySQL root password. You must provide the correct password before the update will proceed.
