Thanks for taking a look. A further detail which may or may not be relevant: When I run the Etcher AppImage, After choosing the .iso file and selecting the device to flash onto, when I hit the “Flash” button, a window pops up asking for my pw, so I assumed Etcher needs to run as root? However, it may be that it is requesting my pw so it can access the microSD card?
