How do you install, update, and remove packages with DNF?

dnf install adds a package plus its dependencies, dnf update upgrades (one package or everything), and dnf remove deletes a package and anything that depends on it.

These are the everyday write operations — and unlike rpm, DNF figures out the dependency graph for you:

dnf install httpd        # shows deps + download/installed size, asks y/N
dnf update               # update the whole system
dnf update kernel        # update only the kernel
dnf check-update         # just list what could be updated

Each command prints a transaction summary and asks for confirmation; add -y to auto-confirm in scripts (dnf install -y httpd).

The remove trap: dnf remove httpd doesn't only delete httpd — it also removes everything that requires httpd (mod_ssl, php modules, web apps…). Always read the removal list before confirming; an unexpectedly long list means you're about to uproot more than you intended.

Kernel note: DNF keeps multiple kernels installed so you can boot an older one if an update misbehaves. uname -r shows the running kernel; dnf list kernel shows which are installed.
