fwupd is a simple daemon allowing you to update some devices' firmware, including UEFI for several machines.
Install the package.
See #Setup for UEFI upgrade if you intend such use.
Certain desktop environments front-end solutions have built-in fwupd support:
- GNOME Software — Will check for updates periodically and automatically download firmwares in the background on GNOME. After a firmware has been downloaded a popup will be displayed in Gnome Software to perform the update.
- KDE Discover — Software center used with Plasma. With the release of KDE Plasma 5.14, a new fwupd backend has been implemented in KDE Discover for firmware updates. These firmware updates are shown with other system updates.
- GNOME Firmware — Application to upgrade, downgrade and reinstall firmware on devices supported by fwupd. It can unlock locked fwupd devices, verify firmware on supported devices and display all releases for a fwupd device.
To display all devices detected by fwupd:
$ fwupdmgr get-devices
To download the latest metadata from the Linux Vendor firmware Service (LVFS):
$ fwupdmgr refresh
To list updates available for any devices on the system:
$ fwupdmgr get-updates
To install updates:
$ fwupdmgr update
- Updates that can be applied live will be done immediately.
- Updates that run at bootup will be staged for the next reboot.
- The root user may be required to perform certain device updates.
Setup for UEFI upgrade
The following requirements should be met:
- Make sure you are booted in UEFI mode, it will not work in legacy boot mode.
- Verify your EFI variables are accessible.
- Mount your EFI system partition (ESP) properly.
espis used to denote the mountpoint in this section.
fwupd will copy all the necessary files over to the
esp, but for this to work, a basic folder layout must be present on your
This constitutes the creation of an
EFI directory on your
# mkdir esp/EFI/
EFIdirectory must be in all upper-case. If you used lower-case, fwupd may detect the
esp/efi/and look for
fwupd.service unit afterwards. You can now
fwupdmgr refresh and
fwupdmgr update. You will be prompted to reboot (into the firmware updater).
Using your own keys
Alternatively, you have to manually sign the UEFI executable used to perform upgrades, which is located in
/usr/lib/fwupd/efi/fwupdx64.efi. The signed UEFI executable is expected in
/usr/lib/fwupd/efi/fwupdx64.efi.signed. Using , this can be achieved by running:
# sbsign --key keyfile --cert certfile /usr/lib/fwupd/efi/fwupdx64.efi
To automatically sign this file when installed or upgraded, a Pacman hook can be used:
[Trigger] Operation = Install Operation = Upgrade Type = Path Target = usr/lib/fwupd/efi/fwupdx64.efi [Action] When = PostTransaction Exec = /usr/bin/sbsign --key keyfile --cert certfile /usr/lib/fwupd/efi/fwupdx64.efi Depends = sbsigntools
Make sure to replace
certfile with the corresponding paths of your keys.
Instead of a pacman hook you can also create a symlink from
/usr/lib/fwupd/efi/fwupdx64.efi.signed and add the file to the
EXTRA_SIGN list in
Finally, you have to change the line containing
DisableShimForSecureBoot=true and restart

Stuck when rebooting
fwupdmgr update reports no error, but the reboot it prompts stuck and holding the power button has no response. Try switching off the power, or press the reset button (on a laptop, it might be a hole on the back) to force-reboot.
No error but no upgrade on reboot
fwupdmgr update reports no error and prompts for reboot (e.g., on BIOS update). However, the system reboots normally (or stuck) and the firmware update does NOT happen.
Possible cause: In BIOS settings changing the boot order must be allowed.
Possible other solution if there are multiple updates pending: Try updating packages one at a time. Use the following to select packages:
$ fwupdmgr update update_ID
update_ID is something like
read-only filesystem error
fwupdmgr 1.5.2 deduces the wrong mount point if bind is used to mount
/boot . Consequently it fails to write the UEFI update file to
fwupdmgr while it should be written to
esp/EFI/arch/fw.) This results in a (misleading) "file system is read-only" error message. In case the update was performed by
Discover (or any other fwupd-capable Update GUI), no error or misleading errors may be shown.
As a workaround, run
umount /boot first if it was bind-mounted to
esp/EFI/arch before, then run
fwupdmgr update to write the UEFI update file to
mount /boot and reboot the system to perform the UEFI update.
UEFI ESP partition not detected or configured
fwupd needsto detect the ESP. As a workaround, the mount point can also be specified manually:
[uefi_capsule] OverrideESPMountPoint=/efi # Change according to your setup

MSR plugin is failing to load
The MSR plugin allows querying the state of DCI, a debugging interface available for Intel CPUs that should be disabled on production machines according to fwupd's documentation.
This plugin needs the
msr kernel module loaded.
msr is a built-in kernel module in all the official Arch Linux kernel packages, but unofficial kernel packages might have it as a loadable kernel module. In the latter case, we need to explicitly load it by automatically loading the msr module with systemd[broken link: invalid section].
