Sorry I can't provide much - I saw only notification of crash
(install on j3400; something else [no-format] over a 18.04 mate install - yellow thumbdrive)
The reason I mentioned my yellow-thumbdrive; is it's cheap, and if touched on some systems, it acts as if removed & re-attached. it's only an issue on some devices (perfectly reliable on some); but I don't use it very often in j3400 so don't know if its reliable, or risky in that device.
