Yes, it was strange, and it was my mistake. I saved balenaEtcher 1.5.57 under a different name alongside v1.5.51, then when I tossed 1.5.51 I didn’t rename 1.5.57 back to basic balenaEtcher, so there was nothing there for the CL to call. It does work now, using sudo.
What I still don’t understand (since I now have nothing to flash) is if the CL call launches something different from the GUI call.
