What is the problem?
Whatever version of Octopi I download, the .img always says it is damaged. I use Etcher to flash it on a 16 GB micro sd card but it always fails.
What did you already try to solve it?
I tried a lot of Octopi versions, it never works, I try flashing it directly from a URL
Have you tried running in safe mode?
No, I have no idea what safe mode is...
Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
I tried the 0.17 version, then the 0.18 version, I'm on windows 10. I use google chrome and WinRAR (free trials for years)
