You can also check that the file has been saved correctly using the ls command (that’s lower case “L” and lower case “S”). Most apps I’ve seen include a guide on how to do this in their instruction page, but if they don’t here is an example of how to use wget: deb file needs to be downloaded from github onto the Raspberry Pi. deb files these days are stored on github. Step 2: Save the file to the Raspberry Pi using wget If you’ve accidentally downloaded the wrong file, the steps below will produce an error. You cannot damage your Raspberry Pi by downloading the wrong file (at least not in any way I’ve seen). Files marked amd64 will not work on Raspberry Pi. Note the difference between amd64 and arm64. Most apps put the processor type in the file name, see the table below for some examples: 32-bit file names deb file if it is the only one available (like for the app I was installing in the picture above). Some configurations support running 32-bit apps in a 64-bit operating system, so feel free to try a 32-bit. deb file (see the table below for examples).

If you’re trying out the new 64-bit Raspberry Pi OS, you should download a 64-bit. deb files available, choose one that is intended for ARM
