How to Update Firmware on Ubuntu or Debian

update_firmware_from_ubuntu_or_debian.md

This is a TL;DR for: https://linuxopsys.com/topics/update-firmware-on-ubuntu-using-fwupd

# Install
su -
apt update
apt install udisks2 fwupd

# Display supported devices 
fwupdmgr get-devices

# Downloading the latest metadata from LVFS
fwupdmgr refresh

# Checking for available firmware updates
fwupdmgr get-updates

# Update the device firmware
# Updates that can be applied live will be done immediately.
# Updates that run at bootup will be staged for the next reboot.
fwupdmgr update

# Optional: Send Telemetry
# fwupd project encourages users to report both successful and failed updates back to LVFS.
# You can send the report using:
fwupdmgr report-history

If fwupdmgr refresh returns errors like Not updatable as UEFI ESP partition not detected you likely need to install udisks2:

apt install -y udisks2
systemctl restart fwupd.service

(This was the case on terminal/no-gui Proxmox 8, aka Debian bookworm)
