System-Upgrade Command

Synopsis

dnf5 system-upgrade <subcommand> [options]

Description

The system-upgrade command is used to upgrade the system to a new major release. First, the download subcommand downloads packages while the system is running normally. Then, the reboot subcommand reboots the system into a minimal “offline” environment to apply the upgrades.

dnf5 system-upgrade is a recommended way to upgrade a system to a new major release. Before you proceed, ensure that your system is fully upgraded (dnf5 --refresh upgrade).

system-upgrade shares many subcommands with the offline subcommand.

Subcommands

clean: See dnf5-offline(8), Offline command
download: Downloads all packages needed to upgrade to a new major release and checks that they can be installed.
log: See dnf5-offline(8), Offline command
reboot: See dnf5-offline(8), Offline command

Options

--releasever=<version>: Required. The version to upgrade to. Sets $releasever in all enabled repos. Usually a number, or rawhide.
--no-downgrade: Behave like dnf5 update: do not install packages from the new release if they are older than what is currently installed. This is the opposite of the default behavior, which behaves like dnf5 distro-sync, always installing packages from the new release, even if they are older than the currently-installed version.
--allowerasing: Allow removing of installed packages to resolve any potential dependency problems.
--number=<boot number>: See dnf5-offline(8), Offline command
--poweroff: See dnf5-offline(8), Offline command

Environment

See dnf5-offline(8), Offline command.
