Is there a known issue with Etcher showing a "Checksums do not match" message for 1.5? The hash is fine, but when flashing to Etcher it shows "1 failed device" with the checksum error. I've tried redownloading the image, using a different SD card, even using a different card reader. Still the same issue.
Thank you for your feedback. So ... you aren't getting the "1 failed device" notice from Etcher? Any ideas about what might be happening? I tried the SD card in RPI4 and the Stellarmate functionality seems to work. I would feel better if I knew the cause for the error.
