Before you begin
Ensure that your existing backup proxy can be upgraded using RPM. If you are upgrading from an older backup proxy version to the latest backup proxy version, RPM upgrade can fail. For example, if you try to upgrade backup proxy using RPM, and in the logs you see a message like:
Vddk 6.0.3 not found on backup proxy. To install rpm please deploy latest backup proxy OVA
If you see a message similar to the one above, you cannot upgrade the backup proxy using RPM. To upgrade backup proxy, deploy the latest backup proxy appliance and reconfigure the virtual machines to use the newly deployed backup proxy.
If you can upgrade the backup proxy using RPM, download the latest backup proxy and perform the following steps.

To check and install the latest updates, you must run the following commands. These commands fix the security vulnerabilities of application packages and kernel by updating them.
Check pending updates
Run the following command:
apt update && apt list --upgradable
Here, apt-update refreshes the list of available package updates.
