How to upgrade [Lenovo] NVMe SSD firmware on Linux

$ sudo sh -c 'curl --location --silent --fail "http://releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.iso" | pv > /dev/<your-usb-drive>'
# note that pv is only there to show progress, it is perfectly fine to redirect curl to the usb drive directly.

then I booted from this drive by pressing F12 on reboot and dumped my NVMe disk to an external hard drive like this:

configures then activates gnome-remote-desktop from the command line
#!/usr/bin/env bash
# run this on the remote terminal machine, as auser with sudo powers, probably through a remote ssh shell
# this will overwrite all the settings it touches
# the name of the user to run these commands as
TARGET_USER=jane
# we need an inlocked desktop session. we can either start a new autologin one or unlock an existing one
