UPDATE OS AGAINST LATEST VULNERABILITIES
What you will need:
SSH Client (Putty, SecureCRT, etc)
This will be used to connect to the ZPC machine via the stack8-console and perform the upgrade.Stack8-console version 3.0.2 or newer
Although the feature was available in earlier releases of Stack8-console, we recommend upgrading to at least version 3.0.2 to address some issues with this feature and for added quality of life improvements.ZPC must be running on the new OS
If you are not sure which version of the OS you are running, check the banner at the top of Stack8-console. The version of the OS should appear as long as you have updated the console to version 3.0.2 or newer.ZPC must be able to reach Internet over port 80
This will allow ZPC to reach Ubuntu’s file servers to download the latest patches. Failing to open port 80 to the internet during the upgrade may cause the upgrade process to fail.
How to upgrade the OS
Open your chosen SSH client and connect to ZPC using your s8admin credentials:
Username: s8admin
Default password: $tacK8 (this password should have been changed during the initial deployment of your ZPC machine)
Select the Update OS Security Vulnerabilities menu item and type “Y” then ENTER when ready to start
The server should now connect to Ubuntu’s remote download servers and update its softwares.
Wait until the process is over, this could take a while (up to two hours in some rare instances)
