Hello everyone, I am beginner to ARMBIAN OS installed on Rock 3A ( 4/64 GB) board. Version of the Armbian OS is "Armbian_22.08.1_Rock-3a_jammy_edge_5.19.5_xfce_desktop.img.xz" and I'm trying to install basic radxa packages such as mraa, PoE function, etc. But I don't know how to and where to update the radxa repository on armbian os.
Still I try to update the repository on /etc/apt/source.list.d/armbian.list , but while updating (apt update) it's throwing an error like "An error occurred during the signature verification". Please help me to solve this issue.
Note : The motive is I have to work with PoE hat, for that mraa packages are essentials. And also I need to work with UART's and please let me know how to add those uarts on overlays of armbianEnv.txt.
Kindly let me know ASAP.
Thanks !
