Followed the instructions here for installing libmraa… https://wiki.radxa.com/Rockpi4/dev/libmraa
But when doing it (and yes, I have verified that I added the source to /etc/apt/sources.list) I get the following error:
root@79966c9:/etc/apt# apt-get install libmraa Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libmraa
Have you actually got this package in your apt repo?
