Chapter 6: Package Management

APT (Ubuntu/Debian)

sudo apt update
sudo apt upgrade -y
sudo apt install nginx
sudo apt remove nginx
sudo apt purge nginx
apt search keyword
dpkg -l | grep nginx

DNF (RHEL/Rocky)

sudo dnf update

Notes

  • apt=high-level (handles deps), dpkg=low-level
  • dnf replaced yum in RHEL 8+
  • Repos: /etc/apt/sources.list.d/ (Ubuntu) or /etc/yum.repos.d/ (RHEL)
