My current version

Today was 6 Sep 2023, but my last update in Nessus was 26 July 2023:

Checking my plugin numbers for my current version so i could compare with my updated version:

Updating Nessus

Step 1: run as root user

sudo su

Step 2: stop the Nessus service

service nessusd stop

Step 3: reset the Nessus configuration, they will ask if u want to proceed, type “y”

/opt/nessus/sbin/nessuscli fix --reset

Step 4: start the Nessus service

service nessusd start

Step 5: register with your “activation code” again

/opt/nessus/sbin/nessuscli fetch --register ABCD-XXXX-YYYY-ZZZZ

Step 6: check if our updates are configured properly

/opt/nessus/sbin/nessuscli fetch --check

Step 7: stop the service

service nessusd stop

Step 8: update the all the nessus core components and plugins

/opt/nessus/sbin/nessuscli update --all

Step 9: open the nessus in browser.

Navigate to Settings > Overview.

Under “Plugins” look for the result of “Last Updated”, if it is showing as N/A then it means it is still compiling plugin updates.

If you mouse over the refresh icon at the top right corner, as shown in the image, you will find the progress of the compiling plugin update.

Let’s wait for it to finish updating.
