Can someone help me with this? I don't know how to get past it. Thanks

[kizniche]

What operating system?

[MSPGrow]

Raspberry PI OS Lite (32-bit)

[kizniche]

No idea about this issue. Try installing again from the master branch.

Thanks Kyle,

Where can I find the master branch?

Thanks, Mark

Also, would it do any good to use the 64-bt Raspberry Pi OS Lite?
