Running balenaOS 2.27.0+rev1 on Raspberry Pi 3+ with PiCAN (dual) interface. The CAN interfaces get initialized correctly but configuring them via /sbin/ip produces error:

root@xxxxxx:~# /sbin/ip link set can0 up type can bitrate 250000 restart-ms 100  
ip: either “dev” is duplicate, or “type” is garbage
