NAME

update-kernel - Linux kernel update tool

SYNOPSIS

update-kernel [options]

DESCRIPTION

update-kernel - script to conveniently update kernel and modules.

It works by installing a new package set along with existing kernel, old kernel is kept so that you don´t end up without a kernel guaranteed to boot (your good old one); by default, it will look for the most recent package of the same flavour (e.g. "std-def") and try to install all the same modules as already installed for that.

OPTIONS

-l, --list

list available kernels

-a, --all

install all kernel modules

-i, --interactive

interactive modules install

-H, --headers

-A modulename

-D modulename

-f, -y, --force

-t, --type

install kernel with specified flavour (un-def, std-def, etc)

-r, --release

desired kernel release (allowed formats by example:
old format: alt1, 5.7.19-alt1
classic kernel release: 5.7.19-std-def-alt1
package name: [kernel-image-]std-def-5.7.19-alt1)

-n, --dry-run

perform a simulation of events that would occur but do not actually change the system

-d, --download-only

download packages but don't install

-h, --help

show this text and exit

Run remove-old-kernels to uninstall unused kernels.
