I cannot get firmware updates to apply on a Dell XPS 9360 running Ubuntu 18.04. Files are copied to the boot partition and found upon reboot, but the update does not seem to be applied after the reboot has finished.
I recently upgraded this laptop from 16.04 to 18.04 and for the first time I received a notification that firmware updates are available. Clicking the notification opens Ubuntu Software which shows the available updates:
- Version 188.8.131.52 for XPS 13 9360 TPM 2.0
- Version 0.2.9.0 for XPS 13 9360 System Firmware
After pressing Update All in Ubuntu Software, I can confirm (in a terminal) that
*.cab files have been copied to
/boot/efi/EFI/ubuntu/fw/ and I get asked to reboot.
During reboot, a short messages confirms that the update files are found and the screen blinks a few times. To me this seems as if the system switches into update modes and applies the updates before completing the reboot.
Afterwards, the system boots normally into Ubuntu but updates do not seem to have been applied:
- Ubuntu Software still lists the same updates
fwupdmgrstill lists the same updates
sudo dmidecode -s bios-versionstill shows the old version 2.2.1 instead of 2.9.0
cat /sys/class/tpm/tpm0/ppi/versionshows version 1.3 instead of 1.3.1 (I don't know for sure if this is a valid way to check the firmware version of TPM; when trying to install
tpm-tools, starting trousers.service failed)
- Trying with
fwupdmgrlead to the same results: Files end up in boot partition and are found upon reboot but do not get applied.
- Booting into update manager and manually selecting the
*.capfiles fails as well (could select the file but not proceed because the button stayed grayed out)
My question remains: How can I apply the firmware updates offered by Ubuntu Software and
