Troubleshooting
If you see a message Message recipient disconnected from message bus without replying or /dev/mem mmap failed: Operation not permitted, you'll need to add the iomem=relaxed kernel parameter. The two below commands will do this for you:
sudo sed -i 's/quiet/quiet iomem=relaxed/g' /etc/default/grub
sudo update-grub
If you see a message that says the version numbers don't match, please use:
fwupdmgr update --force
If you see Failed to connect to daemon: Error calling StartServiceByName for org.freedesktop.fwupd: Failed to activate service 'org.freedesktop.fwupd': timed out (service_start_timeout=25000ms), please delete the database with the below command:
sudo rm /var/lib/fwupd/pending.db
