Server Maintenance
H&D's VPS usually run on GNU/Linux Debian distribution.
Updating the system once a week (or every two weeks) is kinda good. It's good to cross-check the Debian mailing-list (debian-lts-announce@lists.debian.org) beforehand to see if anything major needs a security update or particular care.
To upgrade the system, your unix user needs to be in the sudo group. Following the basic process:
sudo apt update, upgrade local db packagessudo apt list --upgradable, show upgradable packagessudo apt upgrade, upgrade packages
To list all installed packages, run:
apt list --installed
