Your mraa package is build on Ubuntu server, it will not run on Debian ARM64 because of dependency issue. Please rebuild it on or hide it from Debian ARM64.
I build mraa on Debian ARM64 from the source code and works fine. But when I run apt-get upgrade, your version overwrote mine.
I had to apt-mark libmraa-rockpi4 “on hold” for now.
If you build libmraa by yourself, you can just remove the libmraa-rockpi4 package.
Since we now have rockpi4 support merged in the libmraa mainline, we may don’t need libmraa-rockpi4 package in the future. The standard libmraa package will support rockpi4 in the future.
