I had logged in my droplet 4, 5 days ago and performed a reboot command. Then again I have logged in just 5 mins ago, and it was showing system restart required. Again I have performed a reboot command. But there were 0 package updates and 0 package upgrades.
It is happening with my DIgitalOcean and UpCloud both of the servers.
So, How Frequent I Should Reboot a VPS?
