Hi @ufocet,
Apparently recent kernel versions (which apt upgrade automatically installs) automatically load the aarch64 architecture by default on Raspberry Pi ≥4, which can then break some armv7 applications.
For some context, this was apparently an intentional design decision by Raspberry Pi, but because it’s behaviour we didn’t expect or know it’s not prepared for in the current BlueOS images. We are discussing it for future ones though.
