Rock 4 SE v1.53 -> "unable to locate package libmraa"

Hello,
I have the newer rock 4 SE v1.53 board with the image “rock-4se_debian_bullseye_kde_b33.img” installed.

The problem is “Unable to locate package libmraa” after sudo apt-get install libmraa.

With an older Rock Pi 4SE board with buster version I didn’t have this problem.

Can someone help me out on this?
Thanks.

We follow upstream naming convention, which means the main package is called libmraa2. You don’t need to set up PPA as described in the upstream documentation, as we already provide the package in our own apt repo.
