Every once in a while, the OS software should be updated.
When logging in to the terminal, there is often a message stating updates are available. To install these, use the following commands:
sudo apt-get update # Fetches the list of available updates sudo apt-get upgrade # Strictly upgrades the current packages sudo apt-get dist-upgrade # Installs updates (new ones)
Once the updates are done, it’s necessary to clean up any old stuff that isn’t used any longer. Use this command:
sudo apt-get autoremove
And finally, it’s necessary to restart the server. The best way to do this is from the console — just shutdown and reboot the machine and you’re good to go.
