Thank you very much for quick response. Amazed!
Last year, I have upgraded all my Prod VMs running on Azure cloud to Ubuntu 16.04.6 LTS.
Now do you recommend to patch them again? As there are no further releases after 16.04.6 LTS.
When I issue the command, # sudo apt list --upgradable
Below is the output.
$ sudo apt list --upgradable
Listing... Done
