@paul-thornton Thanks to both, the upgrade went flawless, and it seems to be much easier doing it from within linux. It gave me a scare though, in that not only I could not make my (VC) pymakr to connect to it, but it crashed the computer a few times. That, until I deleted the directory .vscode from the working folder. Next I have to look into the Lopy4 upgrade (current code 1.18.2 r1)
