Update the appliance

Retivo

1. Open the appliance's console.
2. Choose Update Retivo. The appliance checks download.retivo.ae and shows the new version, if there is one.
3. Confirm. Retivo is down for about a minute while it restarts.

Every update is signed by Retivo and checked before anything changes. The new version is installed next to the current one; if it doesn't start, the appliance switches back by itself and tells you. Your devices, backups and settings stay as they are.

Before a big update you can take a snapshot of the VM in VMware or Proxmox. Delete it after the update has run for a day.

Ubuntu

Ubuntu security updates install by themselves every day. A few, such as a new kernel, take effect at the next restart: choose Reboot in the console menu at a quiet moment, for example once a month.

A new appliance version instead

Sometimes a release also changes the appliance's operating system. In that case import the new image as a new VM, link it, then move your data:

1. In the old Retivo's web interface, export what you need (inventory, credentials) and let the off-box backup copy run. See Keep backups off the box.
2. Remove the old node under Download & setup on dash.retivo.net, then link the new VM.

The release notes say when this is needed.
