Prerequisites: The person following these steps should have good knowledge of Linux shell scripting and must log in with sudo privileges.
Recommended: The update process automatically creates a backup, but we strongly recommend creating a manual backup of eRS database, before proceeding.
1. Install the XML utility
Check if `xmllint` is already installed:
xmllint --version
If the above command says 'xmllint not found', install using the default package manager (apt or yum):
sudo apt install libxml2-utils
2. Change user context to "eRS"
sudo -su ers
cd /opt/ers
3. Execute the update-script
./update.sh
Note: To ensure that the system is fully updated, re-run this script until it displays the message:
“The latest version is already installed.”
4. Finally, restart the service
Exit to the sudo user context and restart ers service:
exit
sudo systemctl restart ers
