I need to upgrade my wife's machine from Ubuntu 18 LTS to 20 LTS at the earliest convenient time (that may be after the end of this academic term to avoid disruption). She runs Ubuntu on her 2-in-1 as evidently SL 7 does not support all of the hardware functionality that she needs. I have found a URL with detailed instructions that I am willing to forward the information as a PDF to whomever has done this and is interested. My understanding is that unlike EL that more or less requires a new install to go from EL N to EL N++, Ubuntu will upgrade in place. If anyone has done this, please reply, preferably off list to [log in to unmask] so that any URLs will not be "modified" by the security filters at my university. Take care. Stay safe. Yasha Karant
