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 the existing kernel. The 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

add kernel headers to install

-A modulename

include (add) external module (by a short name)

-D modulename

exclude (del) external module from install

-f, -y, --force

force kernel upgrade (without confirmation dialog)

-t, --type

install kernel with specified flavour (un-def, std-def, etc), special name 'latest' selects newest flavour

-r, --release

desired kernel release for the current or selected above flavour (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.

EXAMPLES

Download and install the latest un-def kernel:

update-kernel -t un-def

Download and install a specific kernel version (Note: it should exist in

the repository): update-kernel -r 5.15.70-un-def-alt1

EXIT STATUS

update-kernel returns a zero exit status if it succeeds. Non-zero is returned in case of failure.
